- The basic formula for distance is Distance = Speed ร Time. If you are traveling at 60 mph for 2 hours, your distance is 60 ร 2 = 120 miles. In coordinate geometry, distance is calculated using the Pythagorean theorem.
- The distance between two points (xโ, yโ) and (xโ, yโ) is given by the formula: d = โ[(xโ โ xโ)ยฒ + (yโ โ yโ)ยฒ]. This is derived from the Pythagorean theorem where the distance is the hypotenuse of a right triangle.
- To find speed, divide distance by time: Speed = Distance รท Time. For example, if you travel 100 kilometers in 2 hours, your average speed is 50 km/h.
- To find time, divide distance by speed: Time = Distance รท Speed. If you need to cover 150 miles at a speed of 50 mph, it will take you 3 hours.
- In 3D space, the distance between (xโ, yโ, zโ) and (xโ, yโ, zโ) is: d = โ[(xโ โ xโ)ยฒ + (yโ โ yโ)ยฒ + (zโ โ zโ)ยฒ]. It adds a third dimension to the standard 2D distance formula.
- To calculate real-world distance from a map, measure the distance between two points and multiply it by the map's scale. For example, if 1 cm = 10 km and the map distance is 5 cm, the real distance is 50 km.
- Common units include meters (m), kilometers (km), miles (mi), and feet (ft). Scientific calculations often use meters as the SI base unit.
- Distance is the total path length traveled, while displacement is the straight-line distance from the start point to the end point with a specific direction. Displacement can be zero if you return to your starting point.
