Question

Water flows at a rate of 4 / 5 gal in 1/2 minute how many gallons agter 3 minutes

Answer 1

Explanation:

Set this up as a proportion with gallons on the top and minutes on the bottom.

`(g)/(min):((4)/(5) )/((1)/(2) ) =(x)/(3)`

and then you will cross multiply to solve for x, which is the number of gallons that will flow after 3 minutes, assuming that the water's flow rate remains constant. Cross multiplying gives you:

`(12)/(5)=(x)/(2)` and

5x = 24 so

x = 4.8 gallons
