Question

Willie runs 3 miles in 12 minutes. If Willie runs at the same rate, how far can he run in 60 minutes?

A. 19 miles
B. 4.5 miles
C. 45 miles
D. 15 miles

Answer 1

You could either find the unit rate at which Willie runs, or create and solve an equation of ratios:

3 miles 12 min
----------- = ---------
x 60 min

Then 12x = 180, and x = 15 miles (answer)

Answer 2

the answer is D.15
hope this helps :)
