00:00:00.690 --> 00:00:10.170
Determine the unit rate for a group of 990 people who went to the park between the hours of 9:00 and 11:00 AM.
00:00:11.570 --> 00:00:16.630
Between 9:00 and 11:00 AM, there is a time period of two hours.
00:00:17.580 --> 00:00:22.840
This means that 990 people visited the park in two hours.
00:00:23.610 --> 00:00:29.620
As we want the unit rate, we want the number of people per hour or in one hour.
00:00:30.590 --> 00:00:33.110
Two divided by two is equal to one.
00:00:34.070 --> 00:00:38.260
This means we need to divide 990 by two.
00:00:39.420 --> 00:00:46.300
One way of doing this is using the short division bus stop method, giving us 495.
00:00:47.330 --> 00:00:53.080
This means that 495 people, on average, went to the park in one hour.
00:00:54.390 --> 00:00:59.540
The unit rate is therefore 495 people per hour.
