What is n, the total number of minutes it took Ricardo to run 5.5


miles?


Ricardo ran a totalof 10.75 miles on Monday.


He ran 5.5 miles in the morning and the rest of the miles in the


evening.


What is n, the number of miles Ricardo ran in the evening?

He ran 5.5 miles each hour.


What is n, the number of hours Ricardo ran?


Ricardo ran 10.75 hours one week and 5.5 hours the next week.


What is n, the total number of hours Ricardo ran during these


weeks?

Answer 1

Ricardo ran a total of 10.75 miles on Monday.

`n =1.95`

Explanation:

Given

`10.75 = 5.5n`

Required

Which situation represents the equation and solve for n

The options show the relationship between distance, time and speed.

This is calculated as:

`Distance = Speed * Time`

By comparison:

`Distance = 10.75`

`Speed = 5.5`

`Time = n`

So, we can say that:

He ran 10.75 miles (option D)

Solving for n:

Make n the subject in
`10.75 = 5.5n`

`(10.75)/(5.5) = n`

`n = (10.75)/(5.5)`

`n =1.95`
