Answer:
The distance between the docks & island is 44.07 km.
Step-by-step explanation:
Speed of the boat S = 3.4 knot = 6.3 
Time taken by bot to reach the island = 7 hr
We know that the distance is given by
Distance = Speed × Time
Put all the values in above equation we get
D = 6.3 × 7
D = 44.07 km
Therefore the distance between the docks & island is 44.07 km.
I think it's a although I can't really tell.
The correct answer is none of the above.
<h3>What is a line?</h3>
A line is defined as the shortest distance between two points and the point where two lines meet is known as an angle.
From the given figure, the measure of angle a and b are supplementary since the sum of the angles is not 180 degrees.
They are not vertical angles since they do not meet at a point of intersection
The measure of angle a and b are complementary since the sum of the angles is not 90 degrees. Hence the correct answer is none of the above.
