Question

a train overs 120km in one hour.how much distance will it covers will it covers in 45 min

Answer 1

Hii...

First of all , 1 hour = 3600 sec and 45 min = 2700 sec and 120 km = 1,20,000 m

now, according to ques.,

a train covers 1,20,000 m in 3600 sec ,

so speed = distance/time = 120000/3600 = 33.33 m/s

__________________________________

in 2nd case,if speed remains same i.e. 33.33 m/s
and time = 2700 sec

distance = speed × time = 33.33 × 2700 = 89,991 m or, 89 km 991 m ans.
