Given :
You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you travel 250 miles in an hour and a half.
To Find :
Average speed.
Solution :
We know, average speed is given by :
[tex]v=\dfrac{\text{Total distance covered}}{\text{Total time taken}}\\\\v=\dfrac{200+250}{3+1.5}\ miles/hr\\\\v=\dfrac{450}{4.5}\ miles/hr\\\\v=100\ miles/hr[/tex]
Therefore, average speed of the journey is 100 miles/hr.
Hence, this is the required solution.
whats the average velocity
Answer:
A velocity is a vector unit, and average velocity can be described as the displacement divided by the time. The units for velocity can be understood from the definition to be meters/second or in common any distance unit over any time unit. The average speed of a body is described as the distance covered divided by the time elapsed.
Explanation:
the force of speed
Answer:
10 m/s
Explanation:
The average velocity is the slope of the graph.
m = (10 - 0)/(1 - 0)
m = 10/1
m = 10 m/s
What was the caloric theory of heat?
Answer:Caloric theory, explanation, widely accepted in the 18th century, of the phenomena of heat and combustion in terms of the flow of a hypothetical weightless fluid known as caloric. ... The idea of an imaginary fluid to represent heat helped explain many but not all aspects of heat phenomena.

Complete the paragraph to describe binary systems. A binary star system is made of (blank) stars, one of which is brighter than the other. Astronomers are able to detect the dimmer star because its gravity causes the bright star to (blank). Astronomers can also spot the dimmer star by observing a phenomenon called a(n) (black) binary. This happens when the dim star passes in front of the bright star.

WHY DONT TWO OBJECTS MOVE TOWARDS EACH OTHER DUE TO GRAVITATIONAL PULL BETWEEN THEM
Answer:
Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.
