Answer:
3.5 activities per hour
Explanation:
To find the unit rate at which Bill and his classmates completed the activities, we need to divide the total number of activities completed by the total time taken:
- Unit rate = Total number of activities ÷ Total time taken
In this case, the total number of activities completed is 14 and the total time taken is 4 hours. So we can calculate the unit rate as:
- Unit rate = 14 ÷ 4 = 3.5 activities per hour
Therefore, Bill and his classmates completed the activities at a unit rate of 3.5 activities per hour.
