Question

# A ferries wheel can accommodate 60 people in 24 minutes. Number of people the ferry can accommodate in 2 hours is __________.

Hint:

## The correct answer is: 300

### The Ferris Wheel can accommodate 60 people in 24 minutes.We have to find the ratio of no of people and time. Then we will get the rate at which the Ferris wheel is accommodating people. It will gives the value of no of people per minute. The rate will be constant as Ferris Wheel has constant number of seats. So we will use this value to find the number of people in 2 hours.So the equation becomes   We have to be careful that rate is number of people per minuteTo find the number of people in 2 hours, we will first convert 2 hours in minutes.2 hours = 2 × 60 minutes2 hours = 120 minutesSo the equation of rate isWe will rearrange this equation for no of people, as we have to find number of people in 2 hoursFor this we will multiply both sides by TimeTime × Rate = Number of people.Number of people = Time × RateSubstituting the values we have foundNumber of people = 120 ×   Number of people = 20 × 15Number of people = 300Therefore, number of people a Ferris will can accommodate in 2 hours is 300.

We have to be careful about the units. We have to make the units same before further operation.
