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 ?
(In reply to re: One way
Obviously I've included some more minutes for a break (coffee-pause of the engineer). This is convenient for him to avoid to be asleep, after some time he is checking the fix pressure. Just, I forget to specify in it.
Don't mind. Just kidding.
