TSA TSA Problem Solving 3 — Questions and Answers
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?
- 40 seconds (Correct answer)
- 20 seconds
- 10 seconds
- 80 seconds
Correct answer: 40 seconds
Distance divided by speed gives 20 divided by 0.5, which equals 40 seconds.
Question 2: Policy: liquids over 3.4 oz are prohibited in carry-on. A passenger has a 3.0 oz bottle and a 4.0 oz bottle. How many bottles are prohibited?
- 1 (Correct answer)
- 0
- 2
- Depends on the liquid
Correct answer: 1
Only the 4.0 oz bottle exceeds the 3.4 oz limit, so one bottle is prohibited.
Question 3: A queue grows by 10 people per minute and is cleared by 15 people per minute when open. Starting at 100 people, how long until the queue is empty?
- 20 minutes (Correct answer)
- 10 minutes
- 15 minutes
- 100 minutes
Correct answer: 20 minutes
The net clearance is 5 people per minute, so 100 divided by 5 equals 20 minutes.

- 120 (Correct answer)

B absorbs A's 80 passengers on top of its own 40, totaling 120.

- 10 (Correct answer)

- 11
Correct answer: 10
The sequence increases by 2 each time, so 10 follows 8.

- Deny entry until ID is provided (Correct answer)
- Allow entry
- Allow with a warning

Correct answer: Deny entry until ID is provided
Both items are required, and the missing ID means entry must be denied.
