Question

Every minute, 2.2 gallons of water flows from a shower a family of 5 people showers on an average of 9 minutes every morning. how many gallons of water does the family use for showering every morning?

Answer 1

2.2 gallons of water flow every minute. To figure out how much water flows from a shower in 9 minutes, just multiply 9 × 2.2 which equates to 19.8.

If 5 people shower for 9 minutes, just multiply 19.8 × 5 which equates to 99 gallons of water.
