Question
Consider a plane with a velocity relative to the air of 198 m/s in a westerly direction. If the wind has a speed relative to the ground of 56 m/s (in an easterly direction), how long does it take for the plane to travel from one city to another that is due west of the first by 291 km?

t=s/{v(plane)-v(wind}
!!! km/h -> m/s
!!! km/h -> m/s
