Question

A bus covera certain distance in 3 hours 20 minutes at average speed of 45km/h.How long it will take to cover the same distance at speed of 36km/h

Answer 1

Time = 3 hours 20 minute
=3 1/3 hours
Speed = 45 km/h
Distance = speed x time
=45 x 3 1/3
=45 x 10/3
=150 km
So, now the distance = 150 km
Speed = 36 km/h
Therefore, time = distance /speed
=150/36
=50/12
=25/6 hours
=4 1/6 hours
=4 hours 10 minutes
