As it passes over Grand Bahama Island, the
eye of a hurricane is moving in a direction 25 degrees north of west with a speed of 97 km/h. Three hours later, it shifts due north, and its speed slows to 79 km/h.
How far from Grand Bahama is the eye 4.50 h after it passes over the island?

3*97 @ W25N = (263.7,123.0)
1.5*79 @ N = (0,118.5)
add them up: (263.7,241.5)
distance: √(263.7^2 + 241.5^2) = 357.6 km
