36. A bus is running with a uniform speed of 37 km/h. What distance will be covered by bus in 8 h?
- Option : D
- Explanation :
Let the speed of train A and B be 2x
and 7x respectively.
∴Speed = Distance/Time
⇒Speed ∝ 1/Time [distance = constant]
∴ Required ratio, TA : TB = SB : SA
=7:2
- Option : B
- Explanation : Let the distance on one side be 1 km.
Average speed = 2xy/(x+y)
=(2 x 5 x 2)/(5+2) = 20/7 =
