Answer:

Hence amount of time used by both to shell a bushel of peas working together is 6/5 hrs = 72 minutes

Step-by-step explanation:

Amount of time used by Tim is 2hrs

Amount of work done by Tim in 1hr = 1/2

Amount of time used by Jill is 3hrs

Amount of work done by Jill in 1hr = 1/3

Hence amount of work done by both in 1 hr = (1/2) + (1/3) = 5/6

Hence amount of time used by both to shell a bushel of peas working together is 6/5 hrs = 72 minutes
