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.
Answer
Attempt 1 out of 2
Equation:
Answer: mm =
Let mm be the average number of miles Carter would have to ride each day to meet his goal.
Total miles Carter wants to ride = 28.7
Miles Carter has already ridden = 17
Miles left to ride = Total miles - Miles already ridden
Miles left to ride = 28.7 - 17 = 11.7
Number of days left to ride = 3
Average number of miles to ride per day = Miles left to ride / Number of days left
mm = 11.7 / 3
mm = 3.9
Therefore, Carter would have to ride an average of 3.9 miles each day to meet his goal.
