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 ?

	Chamber 1		Chamber 2
0:00	Load Suit A
0:10	Start test (A @ P1)	Load Suit B
0:20				Start test (B @ P1)
1:10	Adjust pressure
1:14	Start test (A @ P2)
1:20				Unload Suit B
1:30				Load Suit C
1:40				Start test (C @ P1)
2:14	Unload Suit A
2:24	Load Suit B
2:34	Start test (B @ P2)
2:40				Adjust pressure
2:44				Start test (C @ P2)
3:34	Unload Suit B
3:44				Unload Suit C
3:54	Eat sandwich, drink beer
