You go to a halloween fair with a big ferris wheel. the wheel has ten seats, and two people are placed on each seat. every minute a seat passes by the exit platform. at 11 a. m. the ferris wheel opens for 30 minutes. after fifteen minutes, the wheel doubles its speed - how many people have ridden the wheel during this time?

90 people have rode in the wheel during the time

Step-by-step explanation:

Given:

Total number of seats = 10

Number of people in each seat  = 2

Total duration of the Ferris wheel  = 30 minutes

After fifteen minutes, the wheel doubles its speed

To Find:

How many people have ridden the wheel during this time  = ?

Solution:

It is given that for every 1 minute , seat is passed

So in 15 minutes

15 x 2 = 30 people passed, meaning that 30 people have ridden the wheel

After 15 minutes the speed was doubled , that is the the number of seats passed will be 2, i.e, 4 people

so 15 x 4 = 60 people passed, meaning that 60 people have ridden the wheel

Thus totally 30+60 =90 people have rode in the wheel during the time

50=33x+22

step-by-step explanation:
