The test of the suits (Posted on 2005-06-07)

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 ?
