Answer: Andrew - 1.875 Michael- 3.125
Explanation:
If Andrew overtakes in 8 hours, we can divide 15 miles by 8 to see how many miles per hour he goes.
15/8 = 1.875
Then we can multiply 1.875 by 3 to see how much he traveled while walking towards Michael.
1.875*3=5.265- the distance he traveled
Now subtract that by 15 to see how many miles Michael walked.
15-5.625=9.375
That means Michael walked 9.375 miles.
Divide 9.375 by 3 to see how many miles he walked per hour
9.375/ 3 = 3.125
