Question

Calculate the time of by a car if it travels 15 km at a speed of 60 km/hr.​

Answer 1

Speed = Distance/Time

or , Distance/ Speed = Time

Speed of a car is 60km/hr

And distance covered by car is 15 km

Hence , 15 / 60 = 0.25 second

Answer 2

Car:- speed=60 kmph

Time=15 hrs

Distance=speed× time

=15×60=900 km

For the train to travel same distance

distance=900 km

speed=90 kmph

Time=

speed

distance

=

90

900
