One tank is filling at a rate of 3/4 gallons per2/3 mins. A second tank is filling at a rate of 5/8 gallons per 1/2 mins. Which tank is filling faster?

Answer 1

9514 1404 393

Answer:

2nd tank

Explanation:

The rate of filling, in gallons per minute, is found by dividing gallons by minutes.

Tank 1

(3/4 gal)/(2/3 min) = (3/4)(3/2) gal/min = 9/8 gal/min

Tank 2

(5/8 gal)/(1/2 min) = (5/8)(2/1) gal/min = 10/8 gal/min

10/8 gal/min is more than 9/8 gal/minute.

The second tank is filling faster.
