Answer
(a) $5340m$
(b) $3330m$
Work Step by Step
(a) We can find the required distance traveled along the west as
$x=v_xt$
We plug in the known values to obtain:
$x=(3.56m/s)(1500s)$
$x=5340m$
(b) We can find the distance traveled towards north as
$y=v_yt$
We plug in the known values to obtain:
$y=(2.22m/s)(1500s)$
$\implies y=3330m$
