​

Answer 1

Answer:

Abdul while driving to school computes the average speed for his trip to be 20 kmh1.

On his return trip along the same route,there is less traffic and the average speed is 30kmh-1.What is the average speed for Abdul's travel?

Answer 2

Explanation:

So,answer will be 9*60/45=12min. As bus travels at 54 km/h excluding stoppages total distance covered is 54 kms in an hour. Now when the bus travels at 45 km/hr it takes 72 mins to travels same distance( Time = Dist/Speed.. t= (54*60)/45). So the excess 12 mins (72-60) is the time taken at stoppages.
