Question

Abigail wants to ride her bicycle 30.4 miles this week. She has already ridden 7 miles.

If she rides for 3 more days, write and solve an equation which can be used to
determine m, the average number of miles she would have to ride each day to meet
her goal.

Answer 1

To find the average number of miles Abigail would have to ride each day to meet her goal, subtract the miles she has already ridden from her goal and divide by the number of remaining days. Abigail would need to ride approximately 7.8 miles each day for the next 3 days in order to meet her goal.

Step-by-step explanation:

To calculate the average number of miles Abigail would have to ride each day to meet her goal, we can use the formula:

m = (30.4 - 7) / 3

Where m represents the average number of miles she would have to ride each day. We subtract the miles she has already ridden (7) from her goal (30.4) and then divide that by the number of remaining days (3) to find the average.

Substituting the values into the formula, we get:

m = (30.4 - 7) / 3

m = 23.4 / 3

m ≈ 7.8

Therefore, Abigail would need to ride approximately 7.8 miles each day for the next 3 days in order to meet her goal.

Answer 2

3m + 7 = 30.4

m = 7.8

Step-by-step explanation:

3m, where m is the average number of miles per day, will represent how many miles she rides in the next 3 days.

She has already ridden 7 miles, so 7 has to be added to 3m in the equation.

Then, the equation has to be set equal to 30.4, because that is her goal for the week

Put this all together:

3m + 7 = 30.4

Solve for m:

3m + 7 = 30.4

3m = 23.4

m = 7.8

So, Abigail has to ride an average of 7.8 miles per day to meet her goal.
