    speed = distance/time,
    You can kind of tell that, because the units of speed is km/h ( or m/s, or miles/hour — depending on the situation).

    Now if you apply your algebra skills, you might discover that

    time = distance/speed

    Plug in the data:
    time = 100 km / (80 km/h)
    After application of algebra skills again you can see that the units will simplify to simply h.
    time = 1.25 h
