Question

Sumit was standing at the railway crossing when a train crossed him at a speed of 40 km/h in 15 seconds, find the length of the train.

Answer 1

Answer:FIRST CONVERT IT INTO m/s

40 x 5/18 = 100/9 m/s

NOW, SPEED = DISTANCE/TIME

AND DISTANCE = SPEED * TIME

= 100/9 X 15

= 500/3. metre

HENCE , THE LENGTH OF THE TRAIN IN 500/3 METRE ( 166.6 m ) approx.

Step-by-step explanation:

Answer 2

Answer:

so the distance covered by it is 166.65m.

Step-by-step explanation:

given data :

speed = 40 km/hr = 40×5/18 = 11.11 m/s & time = 15 seconds

speed = distance/time

11.11 = distance/15

distance = 11.11×15 = 166.65m

so the distance covered by it is 166.65m.
