ANSWER THOROUGHLY AKA WELL I NEED GOOD EXPLANATION

Lelia should be chosen.

Step-by-step explanation:

Leila: 3 laps is going to be 3/5 x 3, which is 9/5. So she can run 1 4/5 in 7 minutes.

Maria: 1 lap is going to be 3/5. So she can run 3/5 in 3 minutes.

If you multiply 3/5 by 2, you're going to get 6/5 in 6 minutes, and then divide it by 6, which is going to give you 1/5 of a lap in 1 minute, multiply that by 7, and get 7/35. This is for Maria. If you divide 9/5 by 7, you're going to get 9/35. This is for Lelia.

Maria: 7/35 of a lap in 1 minute.

Lelia: 9/35 of a lap in 1 minute.

Lelia should be chosen.
