During a bike ride, you cover 16 km in three hours and then cover 20 km in the next hour. What is your average speed in km/hr during the ride?

Answer 1

average speed is total distance divided by total time.

Total distance: 16 km + 20 km = 36 km

Total time: 3 h + 1 h = 4 h

average speed: 36 km / 4 h = 9 km/h
