Jill has a swimming pool in her backyard. It measures approximately 16.4 feet wide and 26.25 feet long. It is an average of 5 feet deep. During a few hot weeks during the summer, some water evaporates from the pool, and Jill needs to add 10 inches of water to the depth of the pool, using her garden hose. Although her water pressure varies, the water flows through Jill's garden hose at an average rate of 10 gallons/minute.

1. Convert all measurements to metric units (meters, cubic meters, and liters). (Reminder: There are 1000 liters in a cubic meter.)

2. How much water (how many liters) will Jill need to add to her pool to return the water level to its original depth? How many gallons of water is this? (Reminder: Volume = Length x Width x Depth)

3. How long will Jill need to run the hose?

Solution Summary

Wherever applicable, this response computes the answers using US as well as UK gallons, as nothing is specified in the question about the choice of US/UK gallons.

Solution Preview

This solution uses following conversion rules to convert liters to gallons and other way round:

1 liter = 0.264172 US gallons (that evaluates to approximately 1 gallon = 3.79 liters)
1 liter = 0.219969 UK gallons (that evaluates to approximately 1 gallon = 4.55 liters)

1. Width of swimming pool = 16.4 feet = 5.00 meters
Length of swimming pool = 26.25 feet = ...
