We are given that the eye of the storm is 450 nautical
miles away and the storm force extends up to 150 nautical miles. So when the
eye is 150 miles away from the community, the outer edges of the storm winds
will begin to affect the community.
Distance the eye has to travel, d = 450 – 150 = 300
nautical miles
Since t=d/s
where s = 15 knots = 15 nautical mile/hr
t = 300/15
t = 20 hours
