Given: A crew averages 50 ft.² per hour. Their next job totals 1500 Square feet.
Required: How many hours will the next job take them.
Explnation:
We can find the hours using unitary method.
50 square feet are averaged in = 1 hour
1 square feet is averaged in = 1/50 hour
1500 square feet is averaged in =(1/50)1500 hours
[tex]\frac{1}{50}\times1500=30[/tex]So, 1500 square feet is averaged in 30 hours.
Final Answer: The next job will take 30 hours.
