Answer:
1. 12 hours, 2. 4.8 minutes
Step-by-step explanation:
Work Formula: 1/A + 1/B = 1/T where A and B is how long each person finishes the work alone and where T is how long both of them finish the work together.
1. Given that A = 6 and T = 4, then:
1/6 + 1/B = 1/4
1/B = 1/4 - 1/6
1/B = 3/12 - 2/12
1/B = 1/12
B = 12 hours
2. Given that A = 8 and B = 12, then:
1/8 + 1/12 = 1/T
3/24 + 2/24 = 5/24 = 1/(24/5)
T = 24/5 or 4.8 minutes
