1. 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. 10
- B. 10
- C. 10
- D. 10
Answer: Option A
Explanation:
Hints : In case of 1 hour,
Without stoppages, the bus goes 54 km
with stoppages the bus goes 45 km
Distance ( 54 - 45) = 9 km
Nows, it goes 54 km in 60 mins
it goes 1 km in 60/ 54 km
if goes 9 km in 60 × 9/ 54 = 10 mins
