Answer:
12/5 inches per hour
Step-by-step explanation:
1) since 5 ft was filled in 25 hours, you could say that 1ft was filled every 5 hours
2) so now we have 1ft in 5 hours
3) we can convert feet to inches. Since 1ft=12 inches, we could replace 1 ft with 12 inches.
4) Finally, divide by 5 to get 1 hour from one side
5) 12/5 inches = 1hour
so the pool is being filled at a rate of 12/5 inches or 2 2/5 or 2.4 inches every hour
