Question

Two joggers run 8 miles and then 5 miles west. What is the shortest distance, to the nearest tenth of a mile they must travel to return to their starting position?

Answer 1

A. 9.4 mi

Explanation:

Sketch a right triangle with legs of 8 and 5. Shortest distance back to the starting point is the hypotenuse (h) of the triangle:

h² = 8² + 5² = 89

h = √89 = 9.43 mi
