Answer: 10 minutes
Step-by-step explanation:
The first thing is to calculate the amount they can paint per minute.
Eric will paint 1/14 per minute
Jessup will paint 1/35 per minute.
Let t represent the time when the work together, then
1/14 + 1/35 = 1/t
49/490 = 1/t
1/10 = 1/t
Therefore , they will spend 10 minutes when working together
We know that there are 3,000 gallons in the swimming pool and that one hose filled it in x minutes (or hours, doesn't matter), while the second hose filled it 4x minutes. Together we have 5x (five parts that hoses have filled), so all we need to do is to divide 3,000 by 5:
3,000 ÷ 5 = 600
Now we can see that one hose filled <u>600 gallons</u>, while the other one filled 4 * 600 = 2,400 gallons.

Answer:
40 years and 20 years
Step-by-step explanation:
Let the father's age be y and son's age x
Father is currently twice son's age i.e 2x
16 years ago, the son was (x-16) years old
the father was (y-16) or (2x-16) years old.........(i)
The second sentence states that the father was 6 times his sons age 16 years ago i.e 6(x-16)yrs old.............(ii)
Equating (i) to (II) gives 2x-16 = 6(x-16)
2x-16 = 6x-96
Collecting like terms, 96-16 = 6x-2x, 80 = 4x, x = 20
Therefore, son's age is 20years and fathers age is twice son's age = 40 years
