A train of length 250 m crosses a bridge of length 120m in 20 seconds. What is the speed of train?
Answer/Solution
66.6
Steps/Work
Sol : (length of train+ length of bridge) = speed of train x Time
(250+120) = 20 x Speed
Speed = 370/20= 18.5 m/s =66.6 km/h
ANSWER=C
(250+120) = 20 x Speed
Speed = 370/20= 18.5 m/s =66.6 km/h
ANSWER=C
