Question

The Martinez family walked three/five of a mile in three/eight of an hour.

What equation can be used to calculate their unit rate in miles per hour?

Answer 1

convert to hour
divide both sides by three to get
1/5 of a mile in 1/8 of an hour
multiply by 8
8/5 of a mile in 1 hour
1.6 miles per hour

Answer 2

We have an equation: (3/5 mile)/ (3/8 hour)= ?
⇒ ?= 8/5 miles/hour
⇒ ?= 1 3/5 miles/hour.

The final answer is 1 3/5 miles/hr~
