Solving a Work Application: Mowing a Golf Course
Apply the problem-solving strategy for work applications to find the time needed for two gardeners to mow a golf course together. If one gardener takes hours alone and another takes hours alone, let be the hours needed together. Their hourly rates are and , respectively, and their combined hourly rate is . The rational equation is: Multiply both sides by the LCD, : Distribute and simplify: Converting to a mixed number gives hours. Since of an hour is minutes, it would take the two gardeners hours and minutes working together.
