Question

Rohini on her way to write her Mathematical Olympiad decided to calculate the speed of the train that she was travelling in. To cover a certain distance with a speed of 45 km/h * r , the train took 8 hours. If it covered the same distance in 5 hours, what would be its speed?

Answer 1

Answer:

answer is 72 km / hr

Step-by-step explanation:

by using formula s = d/ t

Answer 2

Answer it’s speed would be 72km / hr
Speed= d/ t
45 = d / 8
= 45 x 8
= 360 km
II ) S= 360/ 5
S= 72 km/ hr
I hope it’s correct
Thanks
