    I need help with this question
    when jasmine goes to school, she rides her bike 1.00km[e]
    .70, .80[e]..50. When jack goes to school he rides his bike
    .30km[w] and 1.70km (hint: start from school to home)

    a)draw a scale diagram to represent all the inital displacement vectors and resultant displacement vector in their trips to school

    b) what distance and do jasmine and jack travel in getting to school

    Doesn't look like you need more that 2 km in any direction. Maybe choose .25 km per square on regular graph paper?

    When Jasmine goes to school, she rides her bike 1.00 km[e], 0.70km,0.80km[e],0.50. When Jack goes to school on his skate board, he rides his skateboard 0.30km[w] and 1.70km

    A) draw a scale diagram, to represent all the inital displacement vector and the resultant displacement vector in their trips to school. (Hint: start at the school and work back to their homes)

    B)What distance do Jasmine and Jack travel in getting to school?
    C) when jack is at school, what is his position with respect to his home?
    D) if jack takes 30 min to get to his school, what is his average speed?
    E)what is jacks avg velocity for his trip to school?
    F) when jack is at jasmine's house what is his position with respect to his home?

    I'm guessing that they are asking for both the distance and displacement for their trips?

    This link might help you if you are having difficulty distinguishing between the 2.

    I'm sorry. You'll have to show your work. The idea here is to help you, if you are stuck on something, not do it for you.

    I don;t understand what kind of scale to use because o.25 cm as a skale is very confussing.

    Well what scale works best for your paper? I suggested you use .25 km per square given the dimensions you are dealing with. What are the maximum dimensions you need to accommodate?
