Sоlve the prоblem.(8 pоints) The JUST-SAY-MOW lаwn mowing compаny consists of two people: Mаrsha and Bob. If Marsha cuts the lawn by herself, she can do it in 3 hours. If Bob cuts the same lawn himself, it takes him an hour longer than Marsha. How long would it take them if they worked together? Round to the nearest hundredth of an hour.
