Time and Distance
Two cars (A and B) start at the starting line at the same time on a 3-mile long circular track, going in opposite directions. As they drive around the course, they pass each other many times. Exactly one hour after starting, they pass each other for the 33rd time. At this point car A has completed exactly 20 laps. What is the average speed of Car B?
Three friends A, B and C decide to run around a circular track. They start at the same time and run in the same direction. A is the quickest and when A finishes a lap, it is seen that C is as much behind B as B is behind A. When A completes 3 laps, C is the exact same position on the circular track as B was when A finished 1 lap. Find the ratio of the speeds of A, B and C?

Three sprinters X, Y and Z are initially standing at the vertex A of an equilateral triangle ABC of side length ‘a’ units. They start running simultaneously from the point A. X runs from A to B and continue towards C after reaching B. Y runs along the median AD and then continues towards C after reaching D. Z runs from A to C and then towards B after reaching C. If is also known that X reached D, Y reached D and Z reached C all at the same time. What is the distance of Y from D, the moment when X meets Z.
Hello sir , kindly share the solution to this problem-
A started to chase B when B was 27 steps ahead of A. B takes 8 steps for every 5 steps that A takes. 2 steps of A is equal to 5 steps of B. After how many steps did A catch up with B?
