Arianys wants to ride her bicycle 55.5 miles this week. She has already ridden 19 miles. If she rides for 5 more days, which equation could be used to determine, m, the average number of miles she would have to ride to meet her goal?

19m=55.5 − 5

5m=19−55.5

m=55.5−19/5

55.5=19m+5

We are to deduce from the question the equation that may be used to calculate, m, the average number of miles she would have to ride to reach her objective.

Given:

"Arianys wants to ride her bicycle 55.5 miles"

and

"She has already ridden 19 miles"

Hence,

The number of miles she needs to ride more is

55.5 miles - 19 miles

= 36.5 miles

'

If m is the average number of miles she must cycle in 5 days to reach her objective,

Then, we can write that

m = 36.5/5

OR

m = (55.5 - 19)/5

As a result, the equation that may be used to get m is 5m = 55.5 - 19.

C. m = (55.5 - 19)/5 is the right answer.
