Question

Excluding stoppages, the 2 speed of a bus is 60 km/hr and including stoppages, the 2 speed of the bus is 40 km/hr. For how many minutes does the bus stop per hour ?
A) 2 hrs
B) 20 min
C) 40 min
D) 30 min

Answer 1

Due to stoppages, it covers 9 km less.

Time taken to cover 9 km =9x 60min= 10 min

Answer 2

Heyy mate

In 1hr, the bus covers 60 km without stoppages and 40 km with stoppages.

Stoppage time = time take to travel (60 - 40) km i.e 20 km at 60 km/hr.

stoppage time = 20/60 hrs = 20 min
