I = P * r * t

Principal = rs 400
Interest rate = 6%

Tom sees an enormous thundercloud approaching
ikadub [295]

Using the slope concept, it is found that the thundercloud is 6.43 miles above the ground.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.

In this problem, we have that:

  • The angle is of 65º.
  • The vertical distance is the height h.
  • The horizontal distance is of 3 miles, as the sound takes 5 seconds to travel 1 mile, and it took 15 seconds.

Hence:

tan(65º) = h/3.

h = 3 x tan(65º)

h = 6.43 miles.

The thundercloud is 6.43 miles above the ground.
