Hamish rides his bike at an average speed of 22 km/h. How far does he ride in:

1. 2 1/2 hours?

2. 3/4 of an hour?

3. 15 minutes?

Answer 1

1=55 km
2=16.5km
3=5.5km

Answer 2

2 1/2 Hours = 55 km

3/4 Hours = 16.5 km

15 minutes = 5.5 km

Explanation:

2 1/2 Hours is 2.5 in decimal form so you do 22 X 2.5 to get the 55 km

3/4 hours is 0.75 in decimal form so you do 22 X 0.75 to get 16.5 km

15 minutes is 0.25 in decimal form so you do 22 X 0.25 to get 5.5 km
