Question

Gianna wants to ride her bicycle 48.5 miles this week. She has already ridden 18 miles. If she rides for 5 more days, which equation could be used to determine x, the average number of miles she would have to ride to meet her goal?

Answer 1

8.1 miles per day

Explanation:

18 + 5x = 48.5 >> subtract 18 to both sides

5x= 40.5 >> divide by 5 to both sides

x= 8.1 miles
