Janet can fill the order in 2 hours, and Jim needs 3 hours to do the same work.
Let the time to fill the order working together be x
Then, Janet and Jim can fill the order at the rate of 1x per hour
Thus, Janet can fill an order in 2 hours =12 and Jim can do the same in 3 hours =13
Hence, we get an equations:
12+13=1x
3+26=1x
x=65
Zx=1,2 hours
