A blimp is flying at a speed of 40mph and going in a direction of 80 degrees. After 3 hours of flying it turns and travels 1 hou
kykrilka [37]

Bearing is a topic that can be used to <u>locate</u> the <em>position</em> of an object at a given time. Therefore, the blimp is <em>80 m</em> far away from its <u>starting</u> point. And in the<em> North-East </em>direction.

The <u>speed</u> of an object relates the <em>distance</em> it covers to the <u>time taken</u> to cover the said distance.

i.e speed = \frac{distance}{time taken}

⇒ distance = speed x time taken

In the given question, the <u>initial</u> distance covered can be determined as;

distance = 40 mph x 3 h

              = 120 m

The<u> final </u>distance covered can be determined as;

distance = 40 mph x 1 h

              = 40 m

Let the <u>distance</u> from its <em>starting</em> point to its <em>fina</em>l location be represented by x.

Thus applying the<em> Cosine rule</em>, we have:

c^{2} = a^{2} + b^{2} - 2abCos C

x^{2} = 120^{2} + 40^{2} - 2(120 x 40) Cos 90

   = 14400 + 1600 - 9600

x^{2} = 16000 - 9600

   = 6400

x = \sqrt{6400}

 = 80

x = 80 m

Therefore, the <u>distance</u> of the blimp from its <em>starting</em> point to its <em>final</em> destination is <u>80 m</u>.
