1 hour.
6 hours.
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).
twice as long as it takes to dig two holes
About 2 hours if possible. All you have to do is double everything including the time limit. I disagree. A hole with dimensions of all 2 meters is 8 cubic meters. A whole with all dimensions 4 meters is 64 cubic meters. You aren't just doubling the hole. Yes, you are going twice as deep, but you are also making it a bigger hole. If it took you one hour to dig 8 cubic meters, how many hours will it take you to dig 64 cubic meters? That would be 8 hours.
30min. Becaus if it takes 2 to dig one hole in an hour it will take one man 30 becaus you simply cut it in half
4 hours obviously.
You can't dig half a hole. If you dig there is a hole.
two man-hours. limited only by the space available for diggers per hole.
You cannot dig half a hole. It may be only half as big, but it is still a hole. So the answer is a moment. This is an old, old riddle/joke.
It takes 3 x 6 = 18 man hours to dig 12 holes. Therefore it takes 18/12 = 1.5 man hours to dig 1 hole. To dig 9 holes takes 9 x 1.5 man hours = 13.5 man hours If 2 men are working then they take 13.5/2 = 6.75 hours or 6 hours 45 minutes.
hi they did it in 2 days.....:)
10 hours and 40 minutes.
9 hours and 55 minutes.
Assuming they can work in parallel, the answer should be 5. 5 men produce 1 hole per hour in the first example. At that rate, they produce 5 holes in 5 hours. The same 5 men, working at one hole per hour, should be able to produce 100 holes in 100 hours (assuming they don't need sleep, etc.)
a few hours
half a day. There's so such thing as half a hole!
With one foursome a hole, should be four hours. However, it also depends on the skill of the golfers and the difficulty of the course. If the course is quite long and different, the round is sure to take longer.
6 days.
