Problem 12-230

A man can swim at 4 ft>s in still water. He wishes to cross the 40-ft-wide river to point B, 30 ft downstream. If the river flows with a velocity of 2 ft>s, determine the speed of the man and the time needed to make the crossing. Note: While in the water he must not direct himself toward point B to reach this point. Why?

Step-by-Step Solution:
Step 1 of 3

1. Mutual Exclusion Condition The resources involved are non-shareable. Explanation: At least one resource (thread) must be held in a non-shareable mode, that is, only one process at a time claims exclusive control of the resource. If another process requests that resource, the requesting process must be delayed until the resource has been released. 2. Hold and Wait Condition Requesting process hold already, resources while waiting for requested resources. Explanation: There must exist a process that is holding a resource already allocated to it while waiting for additional resource that are currently being held by other processes. 3. No-Preemptive Condition Resources already allocated to a process cannot be preempted. Explanation: Resources cannot be removed from the process
