& show work!

1. suzette ran and bikes for a total of 110 mi in 7 h. her average running speed was 5 mph and her average biking speed was 20 mph.

let x = total hours suzette ran.
let y = total hours suzette biked.

use substitution to solve for x and y. show your work. check your solution.

note: i genuinely appreciate the . i will be sure to mark brainliest as well. you in advance to all that can !

Finding x.

Suzette ran = x

Suzette biked = 4x

7 = x + 4x --) 7 = 5x --)  1.4 = x

Suzette ran for 1.4 hours

Finding y.

Quickest way is to use Suzette biked = 4x and substitute the x for 1.4 to find how much she biked.

4 x 1.4 = 5.6

1.4 + 5.6 = 7 hours the total time exercising

And the mileage adds up to.

5(1.4) + 20(5.6) = 119
