    physics problem

    Vf = Vi + A(t)

    8.0 km/h = 24.0 km/h - (0.20 m/(s^2)) t


    Do you have to convert the units so they are all the same?
    Could someone just solve this so I get it? please

    all units must "fit".

    change km/hr to m/s ...

    \frac{km}{hr} \cdot \frac{1000 \, m}{1 \, km} \cdot \frac{1 \, hr}{3600 \, s} = \frac{m}{s}
