Multiple choice

A pipe can fill a swimming pool at a constant rate of 450 gallons per hour. If the swimming pool has a capacity of C gallons, which equation represents the total time T, in hours, required to fill exactly two similar swimming pools?

  1. TC = 225

  2. TC = 450

  3. C = 225T

  4. C = 450T

  5. a
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Rate = 450 gallons/hour. To fill two pools of capacity C, total volume = 2C. Time T = (2C) / 450 = C / 225. Thus, C = 225T.

AI explanation

To fill exactly two similar pools, the total capacity to be filled is 2C gallons. Using the formula Time = Capacity / Rate, the total time is T = 2C / 450. Simplifying the right side gives T = C / 225, and multiplying both sides by T yields TC = 225; however, writing C in terms of T gives C = 225T. The result is C = 225T.
