A bus takes 15 hours to travel from town X to town Y and 12 hours to travel from town Y to Z. Is the speed of the bus increasing or decreasing from town 'Y' to 'Z' as compared to the speed from 'X' to 'Y'? Find out.

Given that, Distance from town 'X' to town 'Y' is = 700 km Distance from town 'Y to town 'Z' is = 520 km Time taken by the bus from X to Y is = 15 hours = 15 h Time taken by the bus from Y to Z is = 12 hours = 12 h We know that, Speed = Distance travelled Time taken Speed of the bus from town 'X' to town 'Y' is = 700 15 = 46 . 67 km h - 1 . Similarly, speed of the bus from town 'Y' to town 'Z' is = 520 12 = 43 . 3 km h - 1 . Therefore, speed of the bus is decreasing, when it is traveling from town 'Y' to town 'Z'.

A car travels a distance of 15 km in 20 minutes . Find the speed of the car in km h - 1 .

Given, Distance travelled, d = 15 km Time taken, t = 20 minutes = 20 60 = 1 3 h Speed of the car in km h - 1 is given by, Speed = Distance time = 15 km 1 3 h Speed = 45 km h - 1 .

A bus takes 15 hours to travel from town X to town Y and 12 hours to travel from town Y to Z. What is the average speed of the bus throughout journey?

Given that, Total distance from town 'X' to town 'Y' and town 'Y to town 'Z' is = 700 km + 520 km = 1220 km Total time taken by the bus from X to Y and Y to Z is = 15 hours + 12 hours = 15 h + 12 h = 27 h We know that, Average speed = Total distance travelled Total time taken = 1220 27 = 45 . 2 km h - 1

A car travels a distance of 15 km h - 1 in 20 minutes . Find the speed of the car in m s - 1 .

Given, Distance travelled by car = 15 km = 15 × 1000 = 15000 m Time taken by the car to cover the given distance = 20 min = 20 × 60 = 1200 s The speed of car is given by, Speed = Distance Time Therefore, Speed = 15000 m 1200 s = 12 . 5 m s - 1

A bus takes 15 hours to travel from town X and Y and 12 hours to travel from town Y to Z. Calculate the speed of the bus from town 'X' to town 'Y'.

Given that, Distance from X to Y is = 700 km Time taken by the bus from X to Y is = 15 hours = 15 h We know that, Speed = Distance travelled time taken = 700 15 = 46 . 67 km h - 1 Speed of the bus from town 'X' to town 'Y' is 46 . 67 km h - 1 .
