Tambaya da Amsa: <eng> Jerry has to walk to the sink / recycling bin 28 cans / 4 cans per trip = 7 trips. The round trip takes 10 seconds per way * 2 ways = 20 seconds. Counting the time he spent pouring out the cans and the time the round trip took, he spent 20 seconds per trip + 30 seconds per trip = 50 seconds per trip. With 7 round trips, he spent 50 seconds per trip * 7 trips = 350 seconds.
