The rate given to us in the problem is 45 people per 25 minutes. The first step is to convert this rate to people per hour. To do that, multiply your rate by 60, since there are 60 min per hour.
Now your rate is 45*60/25 people per hour. This can be simplified to 108 people per hour.
Now just multiply that number by two to see how many people can ride in 2 hours.
108*2 = 216 people
A: 216 people in 2 hours, at a rate of 108 people per hour.
