workers driveways days
15              18         24 
1                18        24*15
1                1          24*15/18
40              1          24*15/(18*40)
40             22        24*15*22/(18*40)=11

So basically we find the number of days if it's 1 worker and 1 driveway then put the number of workers and then the number of driveways we are required to find?
BRILLIANT. Thank you so much!
