The right answer is, 18+14.
Answer:
It will take them 2 hours and 55 minutes to remove the shingles if they work together.
Step-by-step explanation:
The together rate is the sum of each separate rate.
In this problem:
Jackson's rate is 1/7
Martin's rate is 1/5.
The together rate is 1/x, which is what we want to find.
So
So 2 hours plus 0.9167 of an hour.
An hour has 60 minutes.
0.9167*60 = 55 minutes
So it will take them 2 hours and 55 minutes to remove the shingles if they work together.
