Question

An electric train is moving with a speed of 144km/h. How much distance will it travel in 20s?

Answer 1

Answer:

Given :

speed of train = 144km/hr = 144 × $\frac{1000}{1800}m/s$ (or) 144 × $\frac{5}{18}$ m/s = 8m/s

time = 20 s

=> Distance (D) = speed × time

=> D = 8 × 20 = 160 m

Answer 2

Step-by-step explanation:

speed=144km/h

=(144*5/18)m/sec

=40m/sec

S=d/t

40=d/20

d=40*20

d=800m

The distance covered by the train =800m
