Distance formula

The formula for calculating the distance between two points is expressed as shown:

  • [tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The required coordinates missing are (0, 42.78) and (90.42.78). Substiute the coordinate into the formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]D=\sqrt{(42.78-42.78)^2+(90-0)^2}\\D=\sqrt{(0^2+(90)^2}\\D = 90 units[/tex]

Hence the required distance covered is 90 units
