    On Monday: I walk 20m east then 10m west.

    On Tuesday: I walk 20m west then 10m east

    what were the distance travelled & displacement on (a) Monday and (b) Tuesday?

    My answers:

    Monday - distance 30m, displacement 10m
    Tuesday - distance 30m, displacement -10m

    I'm not 100% sure so any help would be appreciated

    This looks right to me.

    Well displacement is supposed to have a direction as it is a vector quantity, so for Monday displacement is 10m due North of East and for Tuesday displacement is 10m due North of West hope it helped

    Part a you should draw a right angles triangle and solve for the resultant velocity using Pythagoras.

    Part B is a simple t=d/v using the resultant velocity calculated in part a.

    Part c it asks you to calculate the horizontal distance travelled down the bank and it already gives you the horizontal velocity as the current. So d=vt.

    All 3 of your answers I think are correct. Truth be told I haven't done these type of examples in a couple years so was hesitant about c because it took me a while to figure out it was asking for the horizontal distance travelled by the boat.
