Answer:
16 3/4 miles
Step-by-step explanation:
So the goal of this problem is to get Ryan's total driving distance which was made up of:
A 5 3/4 mile trip
A 6 1/2 mile trip
A 4 1/2 mile trip
Start by adding the last two since they have the same denominator
6 1/2 + 4 1/2 = 10 2/2 = 11
11 miles plus 5 3/4 miles
11 + 5 3/4 = 16 3/4
He drove at total of 16 3/4 miles
