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
