Katarina [22]

Answer:

It will take 56 seconds

Step-by-step explanation:

A water hose used one -eighth of a gallon of water and every second. This means that the flow rate is

1/8 gallon per second.

If Halsey need to fill up 7 gallons sized containers, let x represent the number of seconds that it will take Halsey to fill up 7 gallons. Therefore,

1/8 gallons = 1 second

7 gallons = x seconds.

Cross multiplying,

1/ 8 × x = 7 × 1

x/8 = 7

x = 8 ×7 = 56 seconds
