Discus Throws at School Meet: Vector Diagram

[halb]

in the school track and field meet, three competitiors participated in the senior division discus event. the second competitior threw the discus about one and a half times as far as the first, however the third competitor threw it only about four fifths as far. draw a vector digram representing the displacements of the discus for the three competitors assuming that all throws were in roughly the same direction

well, since the first thrower seems to be the baseline, give it a vector of arbitrary length and then draw the others in relation to it.
