Bibi can run 4 miles in 56 minutes. how many miles does bibi run if she runs for 42 minutes?

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 0.71, after rounding.

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

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