iBotPeaches Posted May 16, 2009 Report Posted May 16, 2009 There are 4 dudes trying to get across to the island. They have one boat. One person ALWAYS must drive the boat to and from the island. Each person however drives at their own speed. The time it takes will always inherit the longer time [EX: Ed (10min) with Bob (1min) = 10 minutes] or [steve (5min) with John (2min) = 5 minutes] The problem is, they only have 17 minutes till the boat runs out of gas. FORGOT: Biggest RULE. 2 in the boat at a time. Ed- 10 minutesSteve- 5 minutesJohn- 2 minutesBob- 1 minute The drive back from the island to land is also added to the time. So if John (2) and Bob (1) drive their and back it would be 4 minutes. Since John has the longer time, It will inherit his time of (2 minutes) for both there and back for a total of 4 minutes. Arrange the people to get over there in 17 minutes or less. There are 2 known possibilities. This question (similar just named changes) was on my application for a job.
