Two cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the eastbound car has traveled 15 kilometers. If the two cars are now a straight-line distance of 17 kilometers apart, how far has the northbound car traveled?

This is a straightforward Pythagorean Theorem problem....

  the car distances are each of the legs of a right triangle  .... one is 15 km...and the hypotenuse is 17 km... find the other leg

 

c^2 = a^2 + b^2          c = 17   a =15     find  b
