Answer:

a = 5 1/3

Step-by-step explanation:

a+b+b = 24

a + 2b = 24

b-a =4

a = b - 4

b - 4 + 2b = 24

3b = 24 + 4

b =28/3

substitute this in a = b - 4

a = 28/3 - 4

a = 28/3 - 12/3

a = 16/3

a = 5 1/3

Stu hiked a trail at an average rate of 3 miles per hour. He ran back on the same trail at an average rate of 5 miles per hour.
Andrews [41]
3t = 5(3-t)
3t = 15 - 5t
3t + 5t = 15
8t = 15
t = 15/8
t = 1 7/8 

7/8 * 60 mins = 52.50 minutes

t = 1 hour and 52.5 minutes

It took Stu 1 hour and 52.5 minutes to hike the trail one way.
