Hi there!
Create a proportion to solve for the amount of time required to run 2 kilometers:
8 km in 60 min
2 km in x min
Express as fractions:
Cross multiply:
8 · x = 60 · 2
8x = 120
Divide both sides by 8 to solve for x:
8x/8 = 120/8
x = 15 minutes

3 1/3 mph
2.5 ÷ 0.75 = 3.3
or
5/2 ÷3/4 = 5/2 · 4/3 = 20/6 or 10/3 = 3 1/3
