Elizabeth wants to ride her bicycle 28.6 miles this week. She has already ridden 19 miles. If she rides for 3 more days, write and solve an equation which can be used to determine mm, the average number of miles she would have to ride each day to meet her goal.

The average number of miles she would have to ride each day to meet her goal = 3.2 miles.

Step-by-step explanation:

Given: Elizabeth wants to ride her bicycle 28.6 miles this week.

She already ridden 19 miles.

Number of days she will ride more =3

Let m = average number of miles ridden in a day.

Then,

Total distance = initial distance + (m) (Number of days)

i.e. 28.6 = 19+3m   (Required equation)

Subtract 19 from both sides , we get

Hence, the average number of miles she would have to ride each day to meet her goal = 3.2 miles.
