Question

A cross country skier can complete a 7.5 km race in 45 minutes. What is the skiers's average speed

Answer 1

Average speed can be found with distance/time. In this case the distance is 7.5 km and the time is 45 minutes

7.5 / 45 = 15/90 = 3/18 = 1/6

Their average speed was one km every 6 minutes
