he will dig 7 1 and 1/2 holes
1 hour.
In one hour, Ryan digs 1/5 of the hole. In one hour, Castel digs 1/6 of the hole. So, in one hour, together they would dig 1/5 + 1/6 = 11/30 of the hole. So they require 30/11 hours = 2.7272... hours = 2 hours 44 minutes (approx).
there are 60 minutes in an hour
The dimensions of the garden are irrelevant to the solution In 1 hour the father can dig 1/3 of the garden, and the son can dig 1/4 of the garden Together in 1 hour they can dig 1/3 + 1/4 = 4/12 + 3/12 = 7/12 of the garden The whole garden will take 1 ÷ 7/12 hours = 12/7 hours = 1 5/7 hours = 1 hr 42 6/7 mins They will take slightly less than 1¾ hours to dig the garden together.

Half of an hour = 1/2 hour...(1) Hours in a day = 24 hours and 1 hour = 1/24 day...(2) From the above two results, we get Half of an hour = (1/2)/24 day = 1/48 day
