Rate = 1.875 miles/hour
The distance formula can be used for this since
distance = rate x time
d = rt
To solve for the rate, r, you divide bot sides of the equation by time, t.
d/t = r
I converted the time to a decimal, and used decimals below
Rate = distance/time
Distance = 0.75 mile
Time = 2/5 hour = 0.4 hour
Rate = 0.75 miles/0.4 hour
You can check this by converting the distance to a fraction and doing the division
0.75 miles = 3/4 miles
Rate = 3/4 miles ÷ 2/5 hour
Give it a try.
