A constant speed test measures the speed of the vehicle against a set amount of time.

• A. Not applicable
• B. False
• C. True
• D. Both

Answer: (B)

Speed is distance divided by time. A constant speed test checks whether the vehicle can maintain the same speed over a given distance or over a defined duration, typically by measuring distance traveled in a set time or the time required to cover a set distance. Saying the test measures speed against a set amount of time confuses what is being held constant and what is being calculated. If you fix the time, you’re measuring how far you go in that time, not the speed itself, which would be derived from distance over time. So this statement is not correct. In practice, you’d either measure distance in a fixed time (to assess speed) or measure time to cover a fixed distance (to assess speed as well), but you don’t measure speed directly “against” time.
