The waiting time to ride a roller coaster is 20 minutes when 150 people are in line. How long is the waiting time when 240 people are in line WRITE a proportion

The waiting time will be 32 minutes when 240 people in line.

Step-by-step explanation:

Let us assume that the waiting time is directly proportional to the number of people in the queue.

Equation of direct proportion between variables x and y :  

Put  to find  .

Hence, the waiting time will be 32 minutes when 240 people in line.

32 minutes

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

For 150 people, waiting time = 20 minutes

So, for 1 minute waiting time, number of people = 150 ÷ 20

= 7.5 people per minute

So, for 240 people, waiting time = 240 ÷ 7.5

= 32 minutes.

So, the waiting time when 240 people are in line is 32 minutes.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
