Question

A pilot is flying from Enugu to Lagos to Abuja. With reference to an origin, Enugu is located at (2, 4), Lagos at (8, 12), and Abuja at (20, 3), all numbers being in 100-mile units.

a. Locate the positions of the three cities on a Cartesian coordinate plane.

b. Compute the distance traveled by the pilot.

c. Compute the direct distance between Enugu and Abuja.

Answer 1

(2,4) to (8, 12) = sqr(36+64) = sqr100 = 10 = 1,000 miles from Enugu to Lagos

(8, 12) to (20, 3) = sqr(196 +81) = sqr277 = about 16.6433 = 1,643.33 miles from Lagos to Abuja

(2,4) to (20,3) = sqr(324+1) = sqr325 = 18.02776 = 1,802.78miles from Enugu to Abuja

1,000+1,643.33+1,802,78 = 4,446.11 miles total

all 3 cities are located in quadrant I in the cartesian coordinate system. they almost form a right triangle with hypotenuse 18.03, legs 16.43 and 10, instead of a 90 degree angle, it's a little less
