Question

Juanita is watering her lawn using the water stored in her rainwater tank. The water level in the tank drops 1/3 inches every 10 minutes she Waters. what is the change in the tanks water level after an hour? what is the expected change in the tanks water level after 2.25 hours? if the water tanks level is 4 ft how many days can Juanita water if she waters for 15 minutes a day.

Answer 1

1/3 per 10 min = 6/3 per 60 minutes = 2/ hour

(I multiplied by 6 because there are 6 x 10 minutes in an hour.

2.25 hours x 2 in/ 1 hour = 4.50 in

15 min/day x 1/3 in/10 min = .5 in per day

4 ft x 12in/ft = 48 inches

(48 inches)/(.5 in/ day) = 96 days
