Answer 1

Answer:

Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.

Step-by-step explanation:

Jamal's speed is of x mph.

Diego's speed is of (x + 7) mph.

Opposite directions.

This means that each hour, they will be x + x + 7 = 2x + 7 miles apart.

After 4 hours they are 68 miles apart, how fast is each traveling?

Using a rule of three.

1 hour - 2x + 7 miles apart.

4 hours - 68 miles apart.

$4(2x + 7) = 68$

$8x + 28 = 68$

$8x = 40$

$x = \frac{40}{8}$

$x = 5$

Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.
