The answer is 29/21. 4/6 + 5/7 = 29/21. so theres your answer
-a+7=2a-8
-a+a+7=2a+a-8 add a on both sides
7+8=3a-8+8 add 8 on both sides
15/3=3a/3 divide 3 on both sides
a=5 solution

To find how much time the machine that took the longer job is, you would create an equation in terms of X, the amount of time it takes one of the machines.
Please see the attached picture for the work.

Answer:
9 Miles to be specific 8.95
Step-by-step explanation:
3 miles = 4.83 km
4.83 km = 4830 m
60 seconds X 45 =2700 Seconds
4830 divided by 2700 = 1.78 m/s
you want to know the distance so its speed X time
135 minutes X 60 seconds = 8100 secs
1.78 m/s X 8100 =14418 meters
14418 = 14.418 km
14.418 km = 9 miles
P.S. There is a shorter version but i think this is simpler for me and I use metric units.
