MCQ

A train running at the rate of 40 km/h passes a man riding parallel to the railway line in the same direction at 25 km/h in 48 seconds. Find the length of the train in metres.

• 100 m

• 200 m

• 150 m

• 250 m

#### Solution

200 m

Explanation:

Let length of train = x km

Then, Speed relative to man = (40 – 25) = 15 km/h

According to question,

"x"/15=48/(60xx60)

"x"=1/5 km⇒1/5xx1000 = 200 m

∴ The length of the train = 200 m
