Water has been poured into an empty rectangular tank at the rate of 5 cubic feet per min for 6 minutes.
The length of the tank is 4 feet and the width is one half of the length. How deep is the water in the tank?
A) 7.5 inches
B) 3 ft. 7.5 inches
C) 3 ft 9 inches
D) 7 ft 6 inches
E) 30 ft
Could someone explain this problem to me plz?
Well to be honest, I'm not sure if this question is complete or not. when the water is poured into the empty tank what capacity is it filled to??? half, full, quarter???
Owell well just say full.
6min*5cubic feet = 30cubic feet
4*2*h=8h --> 8h=30 h=15/4 --> 3 ft 3/4 or 3ft 9 inches. NOT 3 ft 7.5 inches b/c 3/4 of a foot is 9 inches.
