JEE MainMathematicsStraight Lines and Pair of Straight LinesNumerical+4 / −1
A man starts walking from the point P(−-− 3, 4), touches the x-axis at R, and then turns to reach at the point Q(0, 2). The man is walking at a constant speed. If the man reaches the point Q in the minimum time, then 50((PR)2+(RQ)2)50\left( {{{(PR)}^2} + {{(RQ)}^2}} \right)50((PR)2+(RQ)2) is equal to ‾\underline{\hspace{2cm}}​.
