- 22
- 24
Correct answer: 21
(12 + 18 + 24 + 30) / 4 = 84 / 4 = 21.
Question 5: A team raised a 40-foot ladder in 8 seconds. What was the average rate in feet per second?
- 4 ft/s

- 250 gpm
- 300 gpm (Correct answer)
- 350 gpm
- 400 gpm
Correct answer: 300 gpm
1,000 - (350 + 350) = 300 gpm remaining.
Question 7: A circular tank has a radius of 5 feet. What is its approximate area? (use 3.14)
- 62.8 sq ft
- 70.5 sq ft
- 78.5 sq ft (Correct answer)
