Answer 1

4person 30mi))(5person 35min)

Answer 2

Step-by-step explanation:

the answer is approximately 230 gallons and if u want exact then

it comes 228.25

explanation is given below:

3 person together fill tank in 25 min hence,

calculate the time of person C that in how much time

he empty the tank so,

(1/A)+(1/B)-(1/C)=1/25

i.e, (1/30)+(1/35)-(1/C)=1/25 .......... we get,

1/C=23/1050,

while, its given the C can empty 5 gallon per min. therefore

(23/1050)=5

and capacity of tank will get if we solve above expression,

we get 228.25
