Digging the hole!

Start from the basis that we know

5 x R = 100 cu. feet and      6 x C = 100 cu. feet

So, R = 20 cu. feet per hour       and      C = 100/6 cu. feet per hour

So,
time for two = 100 / (R + C) = 2.73 hours = 2 hours 44 minutes

Mr Marlow said...  If you haven't worked it out my birthday is 24th December.

Hence on 24th Dec. 2012 I will be 54
54 x 365 = 19710 days
between 1958 and 2012 there are 13 leap years = 13 extra days
19710 + 13 = 19723 days
December has 31 days hence 6 days left in 1958
Total days = 19723 + 6 = 19729 days
