Rosa can run 4 miles in 56 minutes. how many miles does rosa run if she runs for 42 minutes

Answer 1

First, let’s use what we know to determine how many miles Rosa can run in a minute.

We do so by dividing 4 by 56 (4/56), which equals .071, after rounding.

So, Rosa runs .071 miles in a minute. Now we multiply this by 42 to get our final answer.

42 x .071 = 2.98. Using rounding, we know that Rosa can run 3 miles in 42 minutes.

Answer 2

You can work this as a proportion.

4 miles → 56 min

x miles → 42 min

4(42) = 56x

x = 4(42) / 56 = 3

Rosa runs 3 miles in 42 minutes.
