3. The town of Elena is 24 mi north and 8 mi west of Holberg. A train runs on a straight track between the two towns. How many miles does it cover? Round your answer to the nearest whole number.
a. 17 mi
b. 33 mi
c. 40 mi
d. 25 mi
Think of this as solving the Pythagorean Theorem of a Right Triangle which is a^2 + b^2 = c^2.
let a=8 and b=24 and solve for c
8^2 + 24^2 = c^2
64 + 576 = c^2
640 = c^2
25.298221 rounded to nearest whole number is 25 miles which is answer d
