Question

a train moving at speed of 80 kn/hr crosses a pole in 7 seconds.find the length of the train. ​

Answer 1

Step-by-step explanation:

given

the speed of train=80km/h

time taken by train =7second

find:-

the length of train=distance covered by train in 7 second

so,

we know that,

we have to convert the speed of train in m/s

thus

80*5/18

22.22

so,

length of train=22.22*7

=155.54m
