The test of the suits (Posted on 2005-06-07) Difficulty: 2 of 5
An engineer must test three space suits in two test chambers. Each suit must be tested for 1 hour at each of two pressures.

He takes 10 minutes to load a suit in a chamber, set the pressure, and start the test; 4 minutes to change the pressure in the chamber; and 10 minutes to unload a suit from a chamber.

Knowing that each chamber could contain only one suit at once, and since he can only do one load/unload at a time, can he manage to test the suits in less than 4 hours ?

The goal is to test both suits within a four-hour time frame, which implies that the data is time-sensitive. If you want to the shortest time frame which it takes for him to test the suits, now you have it. Regardless, the answer to the original question is 'Yes.'
