The formula for speed distance time is mathematically given as: Speed = Distance/Time. Where, x = Speed in m/s, d = Distance travelled in m, t= time taken in s. Distance travelled formula. If any of the two values among speed, distance and time are given, we can use this formula and find the unknown quantity.
Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up. For example, lets say you drive a car. You drive it 5 miles east and then 3 miles west.
When you describe distance, you only include the magnitude, the size or amount, of the distance traveled. However, when you describe the displacement, you take into account both the magnitude of the change in position and the direction of movement.
You can use the pythagorean theorem to find the distance between any two points on a coordinate plane as part of the distance formula. People are just mentioning that if the sheep hadn't gone West you would've needed to use the distance formula to figure out the displacement of the sheep because it wouldn't have been immediately obvious.
The distance between two points \(P= (x_1, y_1)\) and \(Q= (x_2, y_2)\) can be found using the following formula: \[PQ = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}.\ _\square\] Construct a triangle \(\triangle PQR,\) where \(R\) has the coordinates \((x_2, y_1)\).
