Marco can walk 2 miles in 30 minutes. At that rate, how many miles will he walk in 90 minutes?
Answered by Steve
well, 90 minutes is 3 times as long as 30 minutes.

So, he'll walk 3 times as far, right?
Answered by Ms. Sue
2/30 = x/90

Cross multiply and solve for x.

3 * 2 = _____ miles

or

2/30 = x/90
30x = 180
x = 180/30
x = ______ miles
