Distance between a, b is 60 miles, c is 50 miles from both. Find shortest distance between c and the highway connecting a b. (2004)
Explanation
 Here, distance between a and b is 60 miles and c is 50 miles from both.
 As c is at the same distance from a and b both, it will be on the line passing through the middle point of a and b. So, we can consider the following figure to know the exact geometry.

Considering cda, measure of angle cda is 90^{0}.

Applying Pythagoras theorem,


Therefore, shortest distance between c and highway joining a and b will be 40 miles.
