Answer:
6 1/3
Step-by-step explanation:
When they work together, they do 1/3 of the job in one hour.
(Bubba) + (Skeeter) = 1/3 job/hour
Subtract 'Bubba'
from each side: Skeeter = (1/3 job/hour) - (Bubba)
Bubba, working alone, does 1/8 of the job in one hour.
Skeeter = (1/3 job/hour) - (1/8 job/hour)
Can you subtract 1/8 from 1/3 ?
Before you can subtract, you'll need a common denominator.
I've got a nice one here . . . 24 .
1/3 = 8/24
1/8 = 3/24
Skeeter = (1/3 job/hour) - (1/8 job/hour)
= (8/24 job/hour) - (3/24 job/hour)
= 5/24 job/hour .
Skeeter mows at the rate of 5/24 field/hour.
The other way to look at that is: 24/5 hour/field = 4.8 hours .
Check:
Bubba: 1/8 field per hour = 0.125
Skeeter: 1/4.8 field per hour = 0.208333...
Together: (0.125 + 0.208333)
= 0.333... field per hour
= 3 hours/field . yay!
