Question

A goods train runs at the speed of 54 km/hr and crosses a 110 me
seconds. What is the length of the goods train?​

Answer 1

Step-by-step explanation:

speed= 54 km/hr

speed = 54*1000/3600

54000/3600

15m/s

d = s*t

15*110

1650m

Answer 2

Answer:

190m

Step by step solution

Speed=54km/hr=15m/s

Let length of train =x

Distance covered by train =length of train+length of platform = x + 110

since speed = distance/time

(110+x)/20= 15

110+x = 300

x = 190

Therefore length of train is 190m.
