- $96
- $108 (Correct answer)
- $72
- $84
Correct answer: $108
2×$12 + 2×$18 + 2×$24 = $24 + $36 + $48 = $108.
Question 2: A train travels 240 miles in 4 hours. At the same speed, how long will it take to travel 360 miles?
- 5 hours
- 6 hours (Correct answer)
- 7 hours

Correct answer: 6 hours
Speed = 240÷4 = 60 mph; time = 360÷60 = 6 hours.
