- A train of length 250 m runs at a speed of 70 km/hr.
Question 1:
A train of length 250 m runs at a speed of 70 km/hr. What will be the approximate time taken to cross any stationary object standing at the railway station? A. 17.23 sec
B. 20 sec
C. 9.5 sec
D. 12.86 sec
Feedback Length of train = 250 m, speed of train = 70 km/hr
Length of train is always considered as distance, and hence here distance = 250 m
1) First convert speed of km/hr into m/s
Speed of train = 70 x 5/18 = 19.44 m/s
2) We know that,
Speed = Distance/Time
Time taken to cross stationary object = 250/19.44
Time taken to cross stationary object= 12.86 sec
