Question

Matt walked 3 miles in 3/4 of an hour. At what rate of speed did he walk in miles per hour?

Answer 1

3/(3/4) = 1/x

Cross multiply and solve for x.

Answer 2

3 miles in 3/4 an hour mean 3/4 is 45 minutes

so 15 minutes is 1 mile , and then 1 hour is 4 miles

can i just use 3/0.75 = 4 miles
