Any cycled a distance of 20km in 150 minutes. What was her average speed in km/h
Show workings
Average speed (km/h) = Total distance (km) ÷ Total time (hours)
Total distance in km = 20 km
Total time in hours = 150 ÷ 60 = 2.5 hours
Average speed (km/h) = 20 km ÷ 2.5 hours
Average speed = 8 km/h
Therefore, the average speed of Any was 8 km/h.
