Question 1:
A train is 360 meter long is running at a speed of 45 km/hour. In what time will it pass a bridge of 140 meter length? A. 20 seconds
B. 30 seconds
C. 40 seconds
Feedback Speed = 45 Km/hr = 45*(5/18) m/sec
= 25/2 m/sec
Total distance = 360+140 = 500 meter
Time = Distance/speed
= 500*2/25= 40 seconds
= 25/2 m/sec
Total distance = 360+140 = 500 meter
Time = Distance/speed
= 500*2/25= 40 seconds
D. 50 seconds
