    Fyi, this is the chemistry section so

    convert each

    30 meters per second

    kilometers per hour

    1000 meters=1 kilometers

    60 seconds=1 hour so

    30 meters=30/1000 kilometers=3/100=0.03 kilomiters

    1 second=1/60 hours

    0.03 / (1/60)

    make the bottom = 1

    multiply the whole fraction by (60/1) / (60/1)

    1.8 / (60/60) = 1.8/1=1.8km/1h

    the answer is 1.8km/h
