3 seconds
The distance behind the car you are following
The three-second rule is generally a guideline for maintaining a safe following distance while driving, regardless of speed. While it is most commonly applied at higher speeds, it can also be effective at speeds under 40 mph. However, at lower speeds, drivers may find that a shorter following distance is acceptable, provided they remain aware of their surroundings and can react quickly to sudden stops or emergencies. Ultimately, safe driving requires adaptability to the specific conditions and traffic situations.
When following another vehicle, it's generally recommended to maintain a distance of at least three seconds behind it, which can be translated to about 100 feet at highway speeds. This distance allows for adequate reaction time in case the vehicle in front suddenly stops. Always adjust your following distance based on speed, road conditions, and weather.
The distance between two cars while driving should be at least 2–3 seconds of following distance under normal conditions. This allows enough time to react to any sudden stops or changes in traffic flow. It is important to increase the following distance in adverse weather conditions or when driving at higher speeds.
The distance will increase as the speed (absolute value of velocity) increases.
In good weather and clear visibility, drivers should maintain a minimum following distance of at least three seconds to allow sufficient time to react to any sudden changes in traffic conditions. This distance should be increased during adverse weather or when driving at higher speeds.
While driving, one should stay two seconds away from the person in front of them at speeds under 30 mph, adding another second for every 10mph above 30.
To find the average velocity when there are two different speeds, you can use the formula: average velocity = total distance traveled / total time taken. Simply calculate the total distance traveled and total time taken for the two different speeds, and plug these values into the formula to find the average velocity.

Need longer stopping distance.
"Faster" refers to speeds. Miles and kilometers are units of distance, not of speed.
No, 90 miles is not a speed. It's a distance. "Racers reach speeds of more than 90 miles per hour."
