Answer: The coordinate are 
( 5 , 2.5 )
Distance = 5
Step-by-step explanation:
The coordinates of the rest stop will be the mid point between the high school is at point (3, 4) and the stadium in Columbus at point (7, 1).
Mid point = (X1 +X2)/2 , (Y1+Y2)/2
 (3+7)/2 , (4+1)/2 = ( 5 , 2.5 )
The approximate distance between the high school and the stadium will be 
D^2 = (7-3)^2 +( 4-1)^2
Where D = distance 
D^2 = 4^2 + 3^2
D = 5
