Question

Morgan can paint a standard-sized

house in about 5 days. For his latest job, Morgan

hires two assistants. At what rate must these

assistants work for Morgan to meet a deadline of

two days?

Answer 1

To solve this problem you must apply the proccedure shown below:
1. You have that Morgan can paint the house in about 5 days. Therefore, his rate is:
rate=1/5
2. Then the rate that the two assistants must work for Morgan to meet a deadline of two days is:
2(1/5)+x(2)=1
2/5+2x=1
2x=1-(2/5)
2x=3/5
x=3/(5x2)
x=3/10
The answer is: 3/10
