6. A cyclist travels 20 km in 4 hrs. Calculate the speed of the cyclist. 7. At the equator, the earth spins a distance of 25,992miles every day. Calculate the average speed of the Earth in mph. 8. The distance between two cities is 144 km, it takes me 3 hours to travel between these cities, determine my average speed. Calculate Distance = R̅× ...
Example 1. Suppose a dog runs from one end of the street to another end of the street and the street is 80.0 meters across. Moreover, the takes 16.0 seconds to cross reach the end of the street. Now, calculate the speed of the dog? Solution: As we discussed earlier the distance formula can be interchanged to find the speed of the body or object.
Help students learn the difference between distance and displacement by showing examples of motion. As students watch, walk straight across the room and have students estimate the length of your path.
Draw a formula triangle for speed, distance and time. Working clockwise from the top, enter D for distance, T for time and S for speed. Use the formula triangle to work out the correct...
You have just derived the distance formula! Note that given any two points with coordinates (x1, y1) and (x2, y2), the distance, d (also called Euclidean distance), between them is given by the formula below. formula to compute the distance between the following points: 1. (1,1) and (3,7) 2. (-1,5) and (2,9)
