Question

Marcia and Tamara are running a race. Marcia has run 4 km. Tamara has completed 3 4ths of the race and 2.5 km ahead of Marcia. write an equation that represents the relationship between the distances each girl has run.

Answer 1

`y = x +2.5\,km`

Explanation:

The equations for each runner are, respectively:

Marcia

`x = 4\,km`

Tamara

`y = x +2.5\,km`

Race length

`s = (4)/(3)\cdot y`

The relationship between each runner is:

`y = x +2.5\,km`
