A 72-kilometer-per-hour goods train passes a 250-meter-long platform in 26 seconds. What is the freight train's length?
A. 230 m B. 240 m C. 260 m D. 270 m
Explanation: Speed = 72 x 5/18 m/sec = 20 m/sec (explanation).Let's say the train's length is x metres and the time is 26 seconds.As a result, x + 250/26 = 20, x + 250 = 520, x = 270.
