Suppose the time is denoted as t. Between which values of t is the speed of the truck constant?
between t = 6 and t = 8, and between t = 16 and t = 20
between t = 0 and t = 6, and between t = 10 and t = 12
between t = 8 and t = 10, and between t = 14 and t = 16
none of the above

The correct answer is: none of the above.
The speed of the truck is constant when the rate of change of its position with respect to time (velocity) remains constant. In other words, the truck is moving at a constant speed when its acceleration is zero.
None of the given options explicitly state that the acceleration is zero between the given values of t. Therefore, none of the options indicate that the speed of the truck is constant between any specified values of t.
