Marco can walk 2 miles in 30 minutes. At that rate, how many miles will he walk in 90 minutes?
well, 90 minutes is 3 times as long as 30 minutes.
So, he'll walk 3 times as far, right?
2/30 = x/90
Cross multiply and solve for x.
so 30?? i'm sure i'm doing this wrong
no 3 i mean
No.
3 * 2 = _____ miles
or
2/30 = x/90
30x = 180
x = 180/30
x = ______ miles
