i have the answers to these i just need explanations; steps on how to do them
1. Heather and Mathew walk with an average velocity of 0.98 m/s eastward. If it takes them 34 min to walk to the store, what is their displacement?

2.If Joe rides his bicycle in a straight line for 15 min with an average velocity of 12.5 km/h south, how far has he ridden?

3. it takes you 9.5 min ot

    sorry i forgot to finish the last one.
    3. it takes you 9.5 min to walk with an average velocity of 1.2 m/s to the north from the bus stop to the museum entrance. What is your displacement?

    thanks

  • Physics -

    all of these use
    displacement=rate*time

    Pn the first, remember to change min to seconds (34min*60sec/min)

    On the second, 15min is .25hr

    on the last, 9.5min=9.5min*60sec/min
