Working together, Adam and JOhn can harvest a field in 8.18 hours. Had he done it alone it would have taken John 15 hours. Find how long it would take Adam to do it alone

Answer: Adam alone would take 6.82 hours

If John alone would’ve taken 15 hours we subtract 15-8.18 to see how much time Adam took off of the 15 hours by helping. 15-8.8=6.82 hours.

Hope this helps!
