Question

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 1

The equation which can be used to solve the the average number of miles he would have to ride to meet his target is 28.7 = 17 + 3x.

The solve equation is x = 3.9 miles.

How to find the number of miles he will ride each day with an equation?

He wants to ride his bicycle 28.7 miles this week.

He has already ridden 17 miles.

He rides for 3 more days.

The equation which can be used to determine the average number of miles he would have to ride to meet his target can be calculated as follows:

The total distance to ride is 28.7 miles.

Therefore,

28.7 = 17 + 3x

where

• x = number of miles he will travel for the remaining 3 days

Therefore,

28.7 = 17 + 3x

subtract 17 from both sides of the equation

28.7 = 17 + 3x

28.7 - 17 = 17 - 17 + 3x

11.7 = 3x

divide both sides by 3

3x / 3 = 11.7 / 3

x = 11.7  /3

x = 3.9

Therefore, he needs to travels 3.9 miles daily for 3 days.
