Question

- A goods train 250m long is running at a speed of 33km/hr. Behind it another mail train 200m long and running at a speed of 60km/hr. It is runniung in same direction on a different track & after meeting the goods train ovrepasses it. Let us find how long will the mail train take to overpass the goods train.​

Answer 1

Answer:

here is your answer, buddy.

Ans:- Given: Length of goods train = 250 m

speed = 33km/hr.

Length of mail train = 200 m

and speed = 60km/hr.

By the question, we have

since, both the train move same direction. so, their relative velocity = 60 km/hr - 33km/hr

= 27km/hr

$27 \times \frac{5}{18} = \frac{15}{2} m \: per \: sec$

.°. total time to that the mail train take to Passover goods train

$= \frac{d}{v} = \frac{250 + 200}{ \frac{15}{2} } = \frac{450 \times 2}{15} \\ = 60sce \: \\ = 1min$
