Question

which two measurements are needed to calculate velocity?
change in speed and time
starting position and ending position
mass of an object and momentum
distance traveled and time

Explanation:

Velocity is defined as the rate of change of displacement (which is related to distance traveled) with respect to time. The formula for velocity is $v=\frac{d}{t}$, where $v$ is velocity, $d$ is distance traveled, and $t$ is time.

Answer:

D. distance traveled and time
