Quiz 4
During the first hour that an amusement park was open 182 people rode the roller coaster. During the
second hour 307 people rode the roller coaster. After the third hour, a total of 921 people had ridden the
roller coaster.
Estimate how many people rode the roller coaster in the third hour.
400 people, if you round the total from the first hour you get 200 people, then the second hour is 300 people, add those you get 500, then the total for the day would round to 900 so 900 - 500 is 400
