Question

Ravi runs 6 miles in 45 minutes. At the same rate, how many minutes would he take to run 4 miles?

Answer 1

\[\frac{ 6 miles }{ 45 minutes }=\frac{ 4 miles }{ ? minutes }\]

you just cross multiply to find the missing number

Answer 2

You could set this up as an equality statement. Like this\[\frac{ 6mi }{ 45\min }=\frac{ 4mi }{ x \min }\]To solve, cross multiply to get 6x = 4(45). 6x = 180. x = 30. So he can run 4 miles in 30 minutes. See that?
