Answer:
Duration of the total trip
Explanation:
Acceleration is defined as the rate of change of velocity of an object:
[tex]a=\frac{\Delta v}{\Delta t}[/tex]
where
[tex]\Delta v[/tex] is the change in velocity
[tex]\Delta t[/tex] is the duration of the change in velocity
Acceleration is measured in meters per squared seconds, [tex]m/s^2[/tex]. Also, we should note that acceleration is a vector quantity, so in order to completely define acceleration we also need to specify the direction.
