Question 1035030
Hi there,
Distance formula:-
√(x2 - x1)^2 + (y2 - y1)^2
(-7,4) -> (7,4)
√(7 - (-7))^2 + (4 - 4)^2
√(7 + 7)^2 + (0)^2
√196 
(7,4) ->(-5,-7)
√(-5 - 7)^2 + (-7 - 4)^2
√(-12)^2 + (-11)^2
√144 + 121
√265
(-5,-7) -> (-7,4)
√(-5 -(-7))^2 + (4 - (-7))^2
√(-5 + 7)^2 + (4 + 7)^2
√(2)^2 + (11)^2
√4 + 121
√125
Total mileage =
√196 + √265 + √125
= 41.46 miles.
Hope this helps :-)
