A scooter travels 40 km at 20 km/hr and returns 60 km at the same speed. What is the average speed?
20 km/hr
The scooter travels the onward distance of 40 km at 20 km/hr and returns 60 km at the same speed of 20 km/hr.
Since both legs of the journey are covered at the identical speed of 20 km/hr, the average speed over the whole journey is also 20 km/hr.
Hence, the average speed is 20 km/hr.
