9)Deandre runs 4 miles in 30 minutes. At the same rate, how
many minutes would he take to
run 10 miles?

75 minutes or one hour and 15 minutes

Step-by-step explanation:

[] We can set up a ratio and cross multiply to find our answer

    -> x will be the minutes taken to run 10 miles

[] Set up an equation

[] Cross multiply

4x = 300

-> Divide both sides of the equation by 4

x = 75 minutes
