Simplify, we get,
Adding like terms, we have,
Thus, the product of
Let’s use the law of cosines to solve this problem. The law of cosines states that for any triangle with sides a, b, and c, and angle C opposite to side c, the following equation holds: c^2 = a^2 + b^2 - 2ab cos. In our case, we know that the patrol boat travels at a speed of 15 knots and the fishing boat travels at a speed of 2 knots. After 1 hour, the fishing boat sends a distress signal, which is picked up by the patrol boat. If the fishing boat does not drift, we can assume that it has traveled 2 nautical miles in one hour . Let’s call the distance between the patrol boat and the fishing boat “d”. We can use the law of cosines to solve for “d” as follows:
d^2 = 15^2 + 2^2 - 2(15)(2)cos(105°) d^2 = 225 + 4 - 60cos(105°) d^2 = 229.8 d ≈ 15.16 nautical miles
Therefore, it will take the patrol boat approximately 1.011 hours to reach the fishing boat at a speed of 15 knots .

Answer:
48 metres.
Step-by-step explanation:
How far does the cyclist travel in 3 seconds:
First, find how far the cyclist goes in 1 second:
320 metres = 20 seconds
? = 1 second
320 ÷ 20 = 16 metres
The cyclist travels 16 metres in 1 second.
How far does the cyclist travel in 3 seconds:
1 second = 16 metres
3 seconds = ?
16 × 3 = 48 metres.
The cyclist travels 48 metres in 3 seconds.
