Answer:
Step-by-step explanation:
The distance between point (x1,y1) and (x2,y2) on a coordinate plane is given by expression
In the problem given coordinate points are
(0, a) and (a, 0).
Thus, distance between these points are given by
Thus , expression gives the distance between point (0, a) and point (a, 0) on a coordinate grid.
5in : 200mi
7in : xmi
One inch represents 40 miles.
7 * 40 miles = 280 miles.
The two cities are 280 miles apart.
