Using it's concepts, the average speed and the average velocity are given as follows:

  • Average speed: 40 miles per hour.
  • Average velocity: 0 miles per hour.

<h3>Average speed</h3>

The average speed is given by the quotient between the total distance traveled and the time taken, that is:

Average speed = total distance/time

In this problem, the total distance is of 60 miles(30 miles west + 30 miles south), in a time of 1.5 hours(1 hour west and 0.5 hours south), hence the average speed is given as follows:

Average speed = 60/1.5 = 40 miles per hour.

<h3>Average velocity</h3>

The average velocity is given by the quotient between the displacement and the time taken, that is:

Average velocity = displacement/time

The displacement is the difference between the final position and the initial position. Since the person got back to the start, finish = start, hence the displacement is of zero, as is the average velocity.

A tin is a right circular cylinder with a diameter of 4 meters and a height of 6 meters. What is the surface area of this tin, i
agasfer [191]

Answer:

32 pi m^2

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2pi r^2 + 2 pi rh

   The diameter is 4 meters so the radius is 1/2 of the diameter = d/2 = 2 meters

SA = 2 * pi * (2)^2 + 2 pi *2*6

    = 8pi +24pi

   = 32 pi m^2
