Final answer:
The distance traveled by an object moving at a constant speed of 3.1 m/s as a function of time t is given by the equation d(t) = 3.1 * t.
Step-by-step explanation:
To calculate the distance d that an object has moved as a function of the time spent moving, t, when it is moving at a constant speed, we use the basic kinematic equation d(t) = v * t, where v is the constant velocity. In this case, the object is moving at a constant speed of 3.1 meters per second (m/s). Therefore, the function describing the distance as a function of time, d(t), is simply d(t) = 3.1 * t. This equation implies that the distance traveled is directly proportional to time when the velocity is constant.
