Question:
Excluding stoppages, the speed of a bus is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?
A) 9
B) 10
C) 12
D) 20
Answer B) 10
Explanation:
Distance Travelled in 1hr if the bus does not Stop = 54 km

Difference in distance = 9 km
Time required travelling 9 km
= (9/54) x 60 (1hr = 60 min)
= 10 minutes.
