Answer:
Step-by-step explanation:
Total man-hours = Number of men × Number of hours
Total man-hours = 9 men × 5 hours = 45 man-hours
Now, we can find the time it takes for 15 men to complete the work by rearranging the formula:
Number of hours = Total man-hours ÷ Number of men
Number of hours = 45 man-hours ÷ 15 men
Number of hours = 3 hours
So, 15 men can complete the same work in 3 hours.
