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, T_{A}: T_{B}= S_{B}: S_{A}

=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 =
