Vivian and Noelle both leave the park at the same time but in opposite directions. If Noelle travels five mph faster than Vivian and after 8 hours, they are 136 miles apart. How fast in mile per hour is each traveling?

Let Vivian speed be x
Noelle speed = x+5
Total time =8 hours
From law of motion, Distance = Speed × Time
Distance covered by Noelle = (x+5) × 8 hours
= 8(x+5)
= 8x+40
Distance covered by Vivian = 8x
Total Distance from Vivian to Noelle = 136 miles
Therefore (8x+40) + 8x = 136 miles
(8x+40) + 8x = 136
8x+40+8x = 136
16x = 136-40
16x = 96
x = 6
Vivian is travelling at 6 mph.
Noelle speed = x+5 = 6+5 = 11 mph.
