A port and a radar station are 2 miles apart on a straight shore running east and west. A ship leaves the port at noon traveling northeast at a rate of 15 miles per hour . If the ship maintains its speed and course, what is the rate of change of the tracking angle θ between the shore and the line between the radar station and the ship at 12:30 p.m.? step by step solution
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
