Oh okay, I get it.. So i have to get the difference of the East and West vectors and use pythagorean theorem to find the resultant vector.

A car us driven at a velocity of 72km/h EAST for 0.50hr, 48km/h NORTH for 0.25hr, and 62km/h WEST for 0.50hr. Calculate the magnitude of its displacement. Attempt at the solution: Distance = Speed * Time (72 x 0.5) + (48 x 0.25) - (62 x 0.5) = 17km However, the answer in the book...
