Question

The double number line shows that a water park allows 18 people to go down their giant water slide in 3 minutes. Select the double number line that correctly labels the number of people that can go down the slide in 1, 2, and 4 minutes.

a) 6, 12, 24
b) 9, 18, 36
c) 4, 8, 16
d) 5, 10, 20

Answer 1

To determine the number of people that can go down the water slide in 1, 2, and 4 minutes, we calculate the rate of 6 people per minute and then multiply it by the number of minutes to get 6, 12, and 24 people, respectively.

Step-by-step explanation:

The question asks us to find how many people can go down a water slide in 1, 2, and 4 minutes given that 18 people can go down in 3 minutes. To solve this, we can divide the number of people by the number of minutes to find a rate, then multiply this rate by the desired number of minutes.

• First, find the number of people per minute: 18 people / 3 minutes = 6 people per minute.
• Next, calculate the number of people for each time frame:
  • 1 minute: 6 people/min x 1 min = 6 people
  • 2 minutes: 6 people/min x 2 min = 12 people
  • 4 minutes: 6 people/min x 4 min = 24 people

Therefore, the correct selection is (a) 6, 12, 24.
