A man starts from the point P(-3,4) and will reach the point Q(0,1) touching the line 2x+y=7 at R. The coordinates R on the line so that he will travel in the shortest distance is

A persons P starts his journey from A and another person Q starts his journey from B, towards each other. The speeds of P and Q are 16 km/h and 25 km/h respectivley What is the ratio of time taken by P and Q to reach B and A respectively?

A person starts from a point A and travels 3 km eastwards to B and then turns left and travels thrice that distance to reach C. He again turns left and travels five times the distance he covered between A and B reaches his destination D. The shortest distance between the starting point and the destination is
