Terrell drove to the mountains at an average
of 40 miles per hour. His return trip, by the
same roads, averaged 50 miles per hour. His
total driving time was 9 hours. How far did
he drive one way?

Terrell drove 200 miles one way

Step-by-step explanation:

Since his trip concluded at 9 hours, let's say that x = time traveled at 40 mph

and 9 - x = time traveled at 50 mph

D = (rate) x (time)

40x = 50(9 - x) Use Distributive property on the right side of the equation

40x = 450 - 50x Add 50x on both sides

90x = 450 Divide by 90 on both sides

We end up with  x = 5  which is the value we need to determine the distance of our first trip, calculated by

D = 40x, or 40(5) = 200 mi

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

the correct answer is the second option
