Time, Speed and Distance

A  $250 \mathrm{m}$ Train is running at the average speed$90 \mathrm{km}/\mathrm{hr}$ . How long will it take to pass a standing man?

A bullock cart has to cover a distance of $120 \mathrm{km}$ in $15 \mathrm{hours}$ . If it covers half of the journey in ${\frac{3}{5}}^{\mathrm{th}}$ time, the speed to cover the remaining distance in the time left has to be:

A thief steals a car at $2.30$pm and drives it at $60$kmph. The theft is discovered at $3$pm and the owner sets off in another car at $75$ kmph when will he overtake the thief ?

The average speed of a train is $\frac{10}{7}$ times the average speed of a car. The car covers a distance of $588 \mathrm{km}$ in $6 \mathrm{hours}$. How much distance will the trains cover in $13 \mathrm{hours}$?

A man walking at ${\frac{4}{5}}^{th}$th of his original speed reaches his destination in $15$ minutes later than the usual time. Then the usual time is:

During a journey of $80 \mathrm{km}$, a train covers the first $60 \mathrm{km}$ with a speed of $40 \mathrm{km}/\mathrm{hr}$ and completes the remaining distance with a speed of $20 \mathrm{km}/\mathrm{hr}$. What is the average speed of the train during the whole journey$?$

A man in a train notices that he can count $21$telephone posts in one minute. If they are known to be $50$metres apart, at what speed is the train travelling?

Study the following information carefully and answer the question given below:

Sita left college for the taxi stand $15 \mathrm{minutes}$ earlier than usual. If she takes $10 \mathrm{minutes}$ to reach the taxi stand. She reached the stand at $5:40 \mathrm{p}.\mathrm{m}.$. What time does she usually leave college for the taxi stand?

A man travels on a scooter from $\mathrm{A}$ to $\mathrm{B}$ at a speed of $30 \mathrm{km}/\mathrm{hr}$ and returns from  $\mathrm{B}$ to $\mathrm{A}$ at $20 \mathrm{km}/\mathrm{hr}$. The total journey was performed by him in $10 \mathrm{hours}$. Find the distance from  $\mathrm{A}$ to $\mathrm{B}$.

A Kinetic Honda covers a distance of $140 \mathrm{km}$ in $2 \mathrm{hours} \mathrm{and} 20 \mathrm{minutes}$ while a car covers the same distance in $1 \mathrm{hour} \mathrm{and} 40 \mathrm{minutes}$. What is the ratio of their speeds?

Sarita and Julie start walking from the same place in the opposite directions. If Julie walks at a speed of $\frac{5}{2} \mathrm{km}/\mathrm{hr}$. and  Sarita at a speed of  $2 \mathrm{km}/\mathrm{hr}$, in how much time will they be $18 \mathrm{km}$apart?

With an average speed of $40 \frac{\mathrm{km}}{\mathrm{hr}}$ a train reaches its destination in time. If it goes with an average speed of $35 \frac{\mathrm{km}}{\mathrm{hr}}$ it is late by $15 \min$. Find the total journey.

A car at the speed of $80 \mathrm{km}/\mathrm{hr}$. What is the speed of the car in meters per second$?$

A thief is noticed by a policeman from a distance of $200$m. The thief starts running and the policeman chases him. The thief and the policeman run at the rate of $10$km and $11$km per hour respectively. What is the distance between them after $6$minutes?

If a car travels $20 \mathrm{km}$ in $2 \mathrm{hours}$ and another $10 \mathrm{km}$ in $3 \mathrm{hours}$, the average speed of the car is:

During a race, the speed of X  is $20\%$ less than that of Y and the sum of the time taken by both of them to complete the race is $108 \mathrm{seconds}$. If the speed of Z is $20\%$ more than that of Y, then find the time taken by Z to complete the same race:

Sheetal decided to run $15$ rounds of a circular track of $400 \mathrm{m}$ in certain time with certain speed. She starts running but after completing some round around the track she reduces her speed by $40\%$ due to which he takes $4 \min$ extra as scheduled. But if she reduces her speed by completing $3$ more rounds she would have reached $2 \min$ earlier than the time she actually reached.

Find the original speed of Sheetal?

A $180 \mathrm{m}$ long train $\mathrm{S}1$ cross a single line bridge in $30 \sec$ after that the train $\mathrm{S}1$ cross another train $\mathrm{S}2$ which is waiting for a signal in a different line in $20 \sec$. The speed of the other train $\mathrm{S}2$ is $72 \mathrm{km}/\mathrm{hr}$ and length is $120 \mathrm{m}$. Then find the time taken by train $\mathrm{S}2$ to cross the same bridge?

Question contains a statement followed by Quantity I and II. Read the information clearly and answer your questions accordingly.

The time taken by a motorboat to travel $1050 \mathrm{km}$ upstream is $40 \mathrm{hours}$ more than the time taken by it to travel the same distance in downstream. The speed of the motorboat in still water is $500\%$ more than that the speed of stream.

Quantity I : How much time the motorboat will take to travel the same distance in upstream?

Quantity II : How much time the motorboat will take to travel $1500 \mathrm{km}$ downstream if due to wind, the speed of stream was increased by $20\%$?

The train $\mathrm{A}$ is running at the rate of $85 \mathrm{kmph}$ crosses a boy who is running at $5 \mathrm{kmph}$ in opposite direction in $15 \mathrm{seconds}$. Train $\mathrm{A}$ crosses train $\mathrm{B}$ which is running at the rate of $31 \mathrm{kmph}$ in the same direction in $40 \mathrm{seconds}$. Find the length of the train $\mathrm{B}$.
