As we need to get answer in seconds, so never forget to convert speed into meter per second.
Speed = 45 km/hr = 45× 5/18 m/sec
= 225/3 m/sec=75m/s
Distance = length of train = 200meter
SOLUTION;
speed=distance / time
t=s×d
t=75×200
t=15000s
Speed = 45 km/hr = 45× 5/18 m/sec
= 225/3 m/sec=75m/s
Distance = length of train = 200meter
SOLUTION;
speed=distance / time
t=s×d
t=75×200
t=15000s

Answer:
16 seconds
Explanation:
t = d / s
d = 200 m
s = 45 Km/s = ( 45 * 1000 ) / ( 60 * 60 ) = 12.5 m/sec
=> t = 200 ÷ 12.5 = 16 sec
