Question 1

A conveyor belt moves bags at 0.5 meters per second over a 20-meter scanning zone. How long is each bag inside the scanning zone?

Accepted Answer

40 seconds

Answer

Distance divided by speed gives 20 divided by 0.5, which equals 40 seconds.

Question 2

1

Answer

Only the 4.0 oz bottle exceeds the 3.4 oz limit, so one bottle is prohibited.
