You can put this solution on YOUR website! Al runs 3 miles in 28 minutes. At the same rate, how many miles would he run in 42 minutes
----------
It's 1.5 times the minutes, he'll run 1.5 times as far.
---------
Or, find his speed:
d = r*t
r = d/t = 3/28 mi/min
---
d = r*t
d = (3/28)*42 miles
-----
another way:
3/28 = d/42
28d = 126
