You're at a halloween fair with a big ferris wheel. the wheel has ten chairs and people are seated two per chair. every minute a chair passes the exit platorm. the wheel opens at 11 am for thirty minutes -- how many people took a ride in that time?
Accepted Solution
A:
The number of people who took ride in the big ferris wheel at a fair can be calculated by proper dimensional analysis. This can be done through the equation below,
n = (number of minutes)(rate at which the chair passes the exit platform)(number of persons per chair)
Substituting the known values to the equation,
n = (30 minutes)(1 chair / minute)(2 persons / chair) n = 60 persons
