Question

Student Council sells bottled water at the cheerleading completion. At this rate, how many cases of bottled water would they sell in 3 hours? ________________________

Cases Sold: 3 and 6
Time (minutes): 20 and 40

Answer 1

27

Explanation:

Lets find the rate of selling:

Let v= the rate of selling, b = number of bottles of water, and t = time:

b over t gives us the
`v=(b)/(t)=(3)/(20)=(6)/(40)=0.15` rate of selling:

3 hours is 60min * 3 = 180 mins, and since v=b/t, vt=b:

(0.15) * 180 = 27 bottles of water
