If a particle has a speed of feet per second and travels a distance (in feet) in time (in seconds), then .
The solution is
A particle has a speed of feet per second and travels a distance (in feet) in time (in seconds)
Speed tells us how fast something or someone is travelling, distance refers to the numerical measurement of how far an object is from a particular place and time refers to an interval separating two events.
The formula can be rearranged for distance as .
The speed of a particle is feet per second and travels a distance (in feet) in time (in seconds), then -
Approximating the Circumference of Earth Eratosthenes of Cyrene (276–195 bc) was a Greek scholar who lived and worked in Cyrene and Alexandria. One day while visiting in
Syene he noticed that the Sun’s rays shone directly down a well. On this date 1 year later, in Alexandria, which is 500 miles due north of Syene he measured the angle of the Sun to be about 6.2 degrees. See the figure. Use this information to approximate the radius and circumference of Earth.
