C)x laps is "0.5x" miles, so if Jose runs "x" laps, then it is "0.5x" miles.
So if Jose wants to run al least 1.5 miles, we have equation "0.5x\\ge 1.5"
D)"x" laps is "0.5x" miles. Since Jose already ran "1.5" miles, "x" laps for him is "1.5+0.5x" miles.
So if Jose wants to run at least 3 miles, we have "1.5+0.5x\\ge 3"
Answer: D
