Final answer:
The answer is true. When traveling 20 miles at 66 mph in a 55 mph zone, you only save 3.6 minutes.
Step-by-step explanation:
The question asks if it is true or false that if you travel 20 miles at 66 mph in a 55 mph zone, you only save 3.6 minutes. The answer is true. To calculate the time saved, first calculate the time taken at 55 mph: 20 miles / 55 mph = 0.36 hours. Then calculate the time taken at 66 mph: 20 miles / 66 mph = 0.303 hours. The difference between these two times is 0.057 hours, which is equivalent to 3.6 minutes.
