First we have to see what they asked. For how many minutes does the bus stop per hour. For that we have to consider the value 54 (exclude stoppages) ie. , if we consider the value 45 the bus has been already stopped so we are considering value 54.

Why to consider 54 rather than 45?

@Girishkumar hi itz simple.
Because 54km in 1 hour.
So 1 km in 1/54 hour.
So 9 km in 9* (1/54) *60 min (1 hour = 60 min).
Because 54km in 1 hour.
So 1 km in 1/54 hour.
So 9 km in 9* (1/54) *60 min (1 hour = 60 min).

@Mr.Shaju
54 - 45 = 9 km is absolutely correct because we are calculating relative results.
54 - 45 = 9 km is absolutely correct because we are calculating relative results.

Hey its 54 kmph and 45 kmph. Can you explain how you got 9 km by subtracting the speeds of bus at different circumstances?

How did 9/54 come?

It is obtained by 54 kmph - 45 kmph = 9 kmph.
