Excluding stoppages, the speed of a bus is 60 kmph and including stopp...
The average speed (including stoppages) = 45 kmph
Distance = speed × time taken
So in 1 hour, distance travelled = 45km
Distance = speed × time taken
So in 1 hour, distance travelled = 45km
The average speed (excluding stoppages) = 60 kmph
At this speed, time taken by bus to travel 45 km = 45/60 = ¾ hrs = 45 minutes
So at a speed of 60kmph, bus can travel distance of 45 km every 45 minutes
⇒ For every hour the bus stops for 60 - 45 = 15 minutes
∴ The bus stops per hour for 15 min
⇒ For every hour the bus stops for 60 - 45 = 15 minutes
∴ The bus stops per hour for 15 min

Excluding stoppages, the speed of a bus is 60 kmph and including stopp...
Let's assume that the total distance traveled by the bus is 60 km (which is a common multiple of 60 and 45).
Let's calculate the time taken by the bus to travel 60 km at a speed of 60 kmph.
Time = Distance / Speed
Time = 60 km / 60 kmph
Time = 1 hour
Now, let's calculate the time taken by the bus to travel 60 km at a speed of 45 kmph (including stoppages).
Time = Distance / Speed
Time = 60 km / 45 kmph
Time = 1.33 hours
We know that 1 hour is equal to 60 minutes.
So, 0.33 hours would be equal to 0.33 x 60 = 19.8 minutes.
Therefore, the bus stops for approximately 19.8 minutes per hour.
Since the given options are in whole numbers, we need to round off the decimal value.
0.8 minutes is closer to 1 minute than 0 minutes, so we round it up.
Hence, the bus stops for approximately 20 minutes per hour.
However, none of the given options are 20 minutes.
So, we need to choose the closest option.
Option C is 15 minutes, which is the closest to 20 minutes.
Therefore, the correct answer is option C) 15 minutes.
Let's calculate the time taken by the bus to travel 60 km at a speed of 60 kmph.
Time = Distance / Speed
Time = 60 km / 60 kmph
Time = 1 hour
Now, let's calculate the time taken by the bus to travel 60 km at a speed of 45 kmph (including stoppages).
Time = Distance / Speed
Time = 60 km / 45 kmph
Time = 1.33 hours
We know that 1 hour is equal to 60 minutes.
So, 0.33 hours would be equal to 0.33 x 60 = 19.8 minutes.
Therefore, the bus stops for approximately 19.8 minutes per hour.
Since the given options are in whole numbers, we need to round off the decimal value.
0.8 minutes is closer to 1 minute than 0 minutes, so we round it up.
Hence, the bus stops for approximately 20 minutes per hour.
However, none of the given options are 20 minutes.
So, we need to choose the closest option.
Option C is 15 minutes, which is the closest to 20 minutes.
Therefore, the correct answer is option C) 15 minutes.
