Answer:
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)
<em>40x = 50(9 - x)</em> -----Use Distributive property on the right side of the equation
<em>40x = 450 - 50x</em><em> </em>-----Add 50x on both sides
<em>90x = 450</em> ------Divide by 90 on both sides
We end up with<em> x = 5 </em>which is the value we need to determine the distance of our first trip, calculated by
<em>D = 40x</em>, or <em>40(5) = 200 mi</em>
