    Betty walks at average speed of 0.8 m/s from the Bay Farm bridge to the Hornet (aircraft carrier). The trip takes her 1.8 hours. How far did she walk in kilometers?

    I divided it but it never came out right can someone explain how to do it?

    You divided? But it is multiplication that you must perform here. speed*times=distance. To remember it easily, look at the units: speed is m/s, time is s. So speed*time = (m/s)(s)=m (=distance). While distance/speed = m/(m/s)=s (=time)

    P.S. Don't forget to convert the hours into seconds before multiplying!

    Speed = distance/time so distance= speed* time. Do you know how many seconds there are in an hour?
