A train 250 m long, running with a speed of 63 km/hr will pass a tree in ____?

38.8

10.8

14.3

To solve this problem, we need to convert the speed from km/hr to m/s and then use the formula:

Time = Distance / Speed

First, let's convert the speed:

63 km/hr = 63 x (1000 m / 3600 s) = 17.5 m/s

Now, let's calculate the time:

Time = Distance / Speed

= 250 m / 17.5 m/s

= 14.3 seconds
