Answer :
This hole has an area of 100 ft².
This means Ryan does 20 ft² per hour
This also mean Castel does 16 2/3 ft² per hour.
20x + (16 2/3)x = 100
(36 2/3)x = 100
x = 30/11 hours (2.727272727272)
This means Ryan does 20 ft² per hour
This also mean Castel does 16 2/3 ft² per hour.
20x + (16 2/3)x = 100
(36 2/3)x = 100
x = 30/11 hours (2.727272727272)
