Explanation
A bus covers a certain distance in 3 hours and 20 minutes at an average speed of 45km/h . How long will it take to cover the same distance of a speed of 36 km/h
Speed=TimeDistance
Speed=45km/hr
Time=331hrs=10/3hrs
Distance=Speed×Time
Distance=45×310
Distance=15×10
∴Distance=150km
Now Speed=36km/hr
Time=SpeedDistance=36150=4366=4hrs and 10mins
