Answer: 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.
