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.

Answers

Answer: Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal.

Step-by-step explanation:

Finding the answer to this problem isn't too complicated, and all we have to do is make and solve an equation. First, we know how many miles Carter wants to ride his bicycle (this is what our equation will be equal to), and how many miles he's completed already (we add that to how many he has to do daily). We also know how many days he has left to complete this goal (multiply the number he has to do daily by three).

All we have to do now is construct a basic equation:

17 + 3x = 28.7

Let's move the 17 over to the other side of the equation. To do that, subtract 17 from both sides.

3x = 28.7 - 17

3x = 11.7

This gives us the amount of miles Carter still has to ride - in total. To find out how many miles he has to ride daily, we just divide 3 from both sides.

3x/3 = 11.7/3

x = 3.9 (miles - don't forget the units!)

Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal. Hope this helps!

Carter will have to ride 3.9 miles everyday
