Answer:
19 5/8 miles
Step-by-step explanation:
First you convert all fractions into improper fraction which are
5 4/8 = 44/8
7 4/8 = 60/8
6 5/8 = 53/8
Then add just the numerators together as the denominator stays the same which looks like 157/8
Then see how many times 157 goes into 8 which is 19 with 5 left over
So you rewrite the answer as 19 5/8 miles
