Joe ran from Point A to Point C and Mike ran from Point B to Point C. About how much farther did Joe run than Mike? Round your answer to the nearest tenth.

Answer 1

Use the Pythagorean Theorem to determine the Distance between two points on the Cartesian Coordinate System. For points A(x₁,y₁) and B(x₂,y₂) that distance formula is:

_, Distance = SQRT ( (x₂−x₁)²+(y₂−y₁)² )

Use the distance formula again to determine the distance between points B and C.

Now, simply subtract the answers and round to the nearest tenth as required.
