12 1/2 min = 12.5 min
2 miles in 12 1/2 minutes =
2 mil / 12.25 min =
8 • 2 mil / 8 • 12.5 min =
16 mil / 100 min = 0.16 mil / min
22 1/4 min = 22.25 min
5 miles in 22 1/4 minutes =
5 mil / 22.25 min =
4 • 5 mil / 4 • 22.25 min =
20 mil / 89 min = 0.22472 mil / min
Unit rate for Mikayla: 0.16 mil / min
Unit rate for Brie: 0.22472 mil / min
Brie runs faster.
