Question

Luis needs to run no less than 120 miles in order to go with the cross country team to a summer training camp. He has thirty days to pre-train for the camp. Which inequality can be used to find how many miles Luis must run each day to meet this goal?

Answer 1

30 days to run at least 120 miles

120/30 = 4

let x = number of days

he needs to run at least 4 miles per day

so x≥4 ( do any of your choices look like this?)
