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?

!!! km/h -> m/s
