If 12 workers can dig a tunnel in 100 days, how long will it take 20 workers to dig the tunnel?
If one person dug the tunnel, it would take 100 days * 12 workers = 1,200 days.
1200 days / 20 workers = 60 days
If one person dug the tunnel, it would take 100 days * 12 workers = 1,200 days.
1200 days / 20 workers = 60 days
