8090 [49]

Answer: Tiffany 15mph, Maggie 20mph

Step-by-step explanation:

Set up the equation 4((x+5) + x) = 140. x+5 represents how many miles Maggie covered in one hour. x represents how much Tiffany traveled in one hour. 140 is the number of miles in total. 4 is the number of hours in total.

Simplify the equation.

(x+5) + x = 35 Divide both sides by 4

2x+5 = 35 Combine like terms

2x = 30 Subtract 5 from both sides

x = 15 Divide both sides by 2

Tiffany traveled 15mph, while Maggie traveled 15+5=20mph.
