Hi!

When we divide a fraction for a fraction we have to multiply the first fraction for the opposite of the second (the one we're dividing for).

Let's do an example.

16/8 : 4/6 = 16/8 * 6/4

Where necessary you can do cross-semplifying.

So, 16 and 4 can be divided both for 4.

8 and 6 both for 2.

So we have 4/4*3/1

You can also semplify numerator and denominator...

4/4 = 1

1*3 = 3

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>
