What is the formula for speed and velocity and give me a prime example please and thank you!

  speed = distance/time

  velocity is speed together with the direction of movement

Explanation:

Every speed limit sign tells you ...

  speed = miles/hour

Of course, the units can vary, but the general form is ...

  speed = distance/time

where "distance" is the magnitude of the displacement in the associated time period.

For example, if you travel 30 miles in 45 minutes, your speed in miles per hour is ...

  speed = (30 mi)/(3/4 h) = 30·4/3 mi/h = 40 mi/h

__

Velocity is a vector quantity, so has both magnitude (speed) and direction. It might be defined as ...

  velocity = displacement/time

where displacement is a vector quantity.

For example, if you travel 30 miles east and 40 miles north in 1 hour, your average velocity is

  velocity = (30, 40)/1 = (30, 40) mi/h . . . . . in (east, north) coordinates

  = 50∠36.87° mi/h . . . . . in "polar" coordinates with the angle being a bearing angle measured clockwise from north

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

i believe the answer is a
