$A$ is twice fast as $B$ and $B$ is thrice fast as $C$ is. The journey is covered by $C$ in $42$ mins. The journey will be covered by $A$ in

If a car runs at $30 kmph$, it reaches its destination late by $15$ minutes, but if it runs at $40 kmph$, it is late by $5$ minutes only. The correct time for the car to complete its journey is:

A man covers a certain distance on his vehicle. If he moves $5 kmph$ faster, he had taken $30$ minutes less. If he moves $4 kmph$ slower, he had taken $30$ minutes more. The distance (in $km$) is

Two cars travel away from each other in opposite directions at $26$ miles per hour and $45$ miles per hour respectively. If first car travels for $30$ minutes and the second car for $40$ minutes. The distance (in miles) between them at the end of their trips is

Two trains start from stations $A$ and $B$ and travel towards each other at speeds of $50 kmph$ and $70 kmph$ respectively. At the time of their meeting, the second train has travelled $100 km$ more than the first. The distance between $A$ and $B$ is:

In covering a certain distance, the speeds of $A$ and $B$ are in the ratio of $5:6$. $A$ takes $50$ minutes, more than $B$ to reach the destination. The time taken (in hours) by $A$ to reach the destination is:

The ratio between speeds of $A$ and $B$ is $3 : 4$ and therefore $A$ takes $30$ minutes more than the time taken by $B$ to reach a destination. If $A$ has walked at double the speed, he would have covered the distance in:

Train $A$ leaves Agra at $5 a.m.$ and reaches Delhi at $9 a.m$. Another train $B$ leaves Delhi at $7 a.m$. and reaches Agra at $10.30 a.m$. The two train cross one another at:
