Question

Tyler runs 8 miles and it takes him 64 minutes. How many miles can he run in 20 minutes?

Answer 1

2 miles

Since 8 x 8 is 64. We would have thought to multiply 2 x 8 but that leaves us to 16. So if we multiply 2 x 10, that gives us 20.

Answer 2

2.5 miles

Explanation:

64/8=20/x

8=20/x

*x *x

8x=20

/8 /8

x=20/8

x=5/2 or 2.5
