Step-by-step explanation:An empty pool being filled with water at a constant rate takes 8 hours to fill to 3/5 of its capacity. How much more time will it take to finish filling the pool?

(A) 5 hr 30 min

(B) 5 hr 20 min

(C) 4 hr 48 min

(D) 3 hr 12 min

(E) 2 hr 40 min

## pls mark as brainliest

Answer:3/10th of pool = 30 minutes

9/10th of pool= x minutes

3/10 * x = 9/10 * 30

3x/10 = 9*3

3x/10 = 27

3x = 270

x = 90 minutes

= 1 and 1/2 hours
