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 m. the average number of miles he would have to ride each day to meet his goal.

## Step 1<br />Carter's goal is to ride a total of 28.7 miles this week. He has already ridden 17 miles. Therefore, the remaining distance he needs to ride is the total goal minus the distance he has already ridden.<br />### \(28.7 - 17 = 11.7\)<br />## Step 2<br />Carter has 3 days left to ride. To find the average number of miles he needs to ride each day, we divide the remaining distance by the number of days.<br />### \(11.7 \div 3 = m\)
