Workkeys Math Practice Test

To determine the total person-hours needed to clear a driveway and pour concrete, you simply add together the time required for each task. In this scenario, breaking up the driveway requires 14 hours, and pouring concrete takes an additional 8 hours. Calculating the total, you would perform the following addition: 14 hours (breaking up the driveway) + 8 hours (pouring concrete) = 22 hours total. Therefore, the total person-hours needed for both activities is 22 person-hours. This aligns with the correct answer.
