Stan can load his truck in 48 minutes. If his brother helps him, it takes them 30 minutes to load the truck. How long would it take Stan's brother working alone to load the truck? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! 1/48+1/x=1/30
1/x=1/30-1/48
1/x=(48-30)/30*48
1/x=18/1440
18x=1440
x=1440/18
x=80 minutes for the brother working alone.
Proof:
1/48+1/80=1/30
(80+48)/48*80=1/30
128/3840=1/30
1/30=1/30
