Carter wants to ride his bicycle 28.7 miles this week. He has already ridden 17 miles. If he rides for 3 more days, write and solve an equation which can be used to determine mm, the average number of miles he would have to ride each day to meet his goal.
Equation:
Answer: m =
m = (28.7 - 17) / 3
m = 11.7 / 3
m = 3.9
Therefore, Carter would have to ride an average of 3.9 miles each day for the next 3 days to meet his goal of 28.7 miles.
