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. Compute the distance traveled by the pilot.

b. Compute the direct distance between Enugu and Abuja.

Answer 1

(2,4), (8,12), (20,3)

(2,4) to (8,12) = sqr(36 +64) = sqr100 = 10 times 100 = 1,000 miles

(8,12) to (20,3) = sqr(14^2 +81) = sqr196+81= sqr277 times 100 = 100sqr277 miles

(2,4) to (20,3) = sqr(18^2 + 1)= sqr325= distance from Abuga to Enugu times 100 miles = 100sqr325 miles

total distance = 10+sqr277+sqr325 times 100 miles

= 1,000+100sqr277 + 100sqr325 miles
