Question

Allie and Bob run together every Sunday.
Allie can run 4 miles in 32 minutes and Bob can
run 3 miles in 22 minutes? Who can run the faster?

Answer 1

Answer:

Bob

Step-by-step explanation:

Allie: 4/32 = 1/8 = 0.125 miles/min

Bob: 3/22 = 0.136 miles/min

Bob is faster

Answer 2

If Allie can run 4 miles in 32 minutes then she can run 1 mile in 8 minutes (both divided by 4). This also means that she can run 3 miles in 24 minutes. Bob can run 2 minutes faster than Allie.
