Question

How long is a train which passes a signal in twenty seconds at a speed of 108 km/h.​

Answer 1

Answer:

The answer is 600m.

Step-by-step explanation:

Distance = Speed × Time = 108 km/h × 20 s = 108/3600s × 20s = 108/180 = 0.6 km = 600m

Answer 2

Length of Train = 600 m if it passes a signal in 20 sec at 108 km/hr

Step-by-step explanation:

Let say Length of Train = D  km

Speed of Train = 108 km/Hr

Time Taken by Train = 20 Secs  = 20/3600 hr

= 1//180  hr

Distance covered = Length of Train in crossing a Signal

Distance = Speed * Time

=> D = 108 * (1/180)

=> D = 108 /180

=> D = 3/5

=> D = 0.6 km

0.6 km = 600 m

Length of Train = 600 m
