What is the shortest distance between circle A defined by (x − 5)2 + (y − 4)2 = 4 and circle B defined by (x − 1)2 + (y − 1)2 = 1? There is some point P on circle A closest to B, and there is another point Q on circle B closest to A. What are the coordinates of P and Q?
What is the probability the distance d between the points is larger than l?
A rectangle has sides 6 and 8. Construct a diagonal of the rectangle, dividing the rectangle into two triangles. Inscribe circle X in one triangle and circle Y in the other triangle. What is the distance between the centers of circles X and Y?
Two buses with uniform speeds of 75 km/hr and 60 km/hr started from stand A at the same time towards stand B. The faster bus after returning from stand B meets slower bus at a distance which is 9 km from stand B. What is the distance between stand A and stand B in km?
A car leaves point A at 3:30 pm and moves towards point B at a uniform speed. A train leaves point B at 4:03 pm and moves towards point A at a uniform speed which is 5/4 that of the car. They meet at 5:15 pm at a point which is 161 km away from point A. What is the distance between point A and point B?
