The time it takes to lay a sidewalk of a certain type varies directly as the length and inversely as the number of men working. If eight men take two days to lay 100 feet, how long will three men take to lay 150 feet?
If 8 men takes 2 days to lay 100 ft, 8 men laid 50ft in 1 day. That means each man laid 6.25ft each day. Now, there are 3 men, doing 6.25ft each man per day, and the job requires 150ft. How long will it take? Tip 1: Total Days = [amount needed to be laid] / [amount laid by 3 men] Tip 2: 150 / [3(6.25)] Tip 3: Answer- 8 days
