Final answer:
To allow a following distance while driving, we need to calculate the distance traveled in a specific time. By converting the speed from mph to ft/s, we can use the formula distance = speed x time to calculate the following distance. In this case, it is approximately 403.35 feet or 5 seconds.
Step-by-step explanation:
To calculate the following distance, we need to convert the vehicle's speed from mph to ft/s.
55 mph = 80.67 ft/s
Then, we can use the formula distance = speed x time to calculate the following distance.
Let's choose option c) 5 seconds as the following distance. Calculating the distance:
distance = speed x time = 80.67 ft/s x 5 s = 403.35 ft
Therefore, if you are driving a 30 ft vehicle at 55 mph, you should allow at least 403.35 feet or approximately 5 seconds of following distance.
