Question

A train covers a distance of 765km in 17hr . How much distance will it covers in 4second

Answer 1

Answer:The train will cover 50m in 4second

Step-by-step explanation:

Given, in 17 hr a train covers a distance of 765 km

Then, the time is 17 hr = 17×3600 s

= 61200 s

and the covered distance is 765 km = 765000 m

∴The distance that the train covers in 1 second = 765000/61200 m

= 12.5 m

Then, the distance that the train covers in 4 seconds = 4×12.5 m

= 50 m
