How do you determine these things: The velocity is positive and increasing; what is the rate at which the velocity increases in this (these) case(s)? What do they mean by the rate here? - How can we describe the variation of speed in this (these) case(s)?

    rate is equal to time

    it is from 0-9 and then say the rate is from 0-4, how? or why?

    the rate in this interval is \[\Delta V/\Delta t\]

    this is the variation of velocity in time( accelaration) a= 2

    m/s²

    I'd recommend taking the table and creating a Velocity vs Time graph...then the rates will simply be the slopes at each point (dV/dT=acceleration).

    Maybe this will help...I interpolated the missing values and did a rough graph. The question is flawed however since the velocity is not always positive.
