No way to tell.  You specified how long it takes the two guys to mow some lawns, but you said nothing about trimming.


If J does 15 in 5, he can do 3 in 1 hour.  D can do 2 in 1 hour.  Together they can mow 5 (2 + 3) in 1 hour, so they can mow 15 in 3 hours.  Can&#39;t tell how much longer it will take if they trim the lawns as well.
