Speed Time and Distance is a very important topic for all entrance exams like GRE/GMAT/CAT/XAT/NMAT and also for competitive exams like Bank P.O, SSC and other recruitment exams.• This course is divided in to ten sections.1. Basic ConceptsThe entire topic of Speed Time and Distance depends on the basic relation/ratio between Speed and Time, Time and Distance, Speed and Time. These ratios are discussed in this section.2. Average SpeedThe special cases of average speed and the short cuts, formulae to solve such questions are discussed in detail.3. Relative SpeedThe relative speed when two objects move in the same direction and opposite direction and related concepts are discussed in this section.4.Meeting PointWhere do two persons meet, when they start from the same end and opposite ends and related concepts are dealt in detail.5.TrainsThe concepts and questions on trains are discussed.6.Linear RacesThe concepts and key points on linear races are discussed in this section.7.Circular TracksThe important points on circular tracks/races are covered in this section.8.ClocksHow to find the angle between the hands of a clock and related concepts are discussed.9.Boats and streams, EscalatorsThe effective speed when a boat travels in a river and a person moving on an escalator are discussed.10.Time ZonesWhen an aircraft travels between two cities which are in different time zones, the actual travel time and related concepts are discussed.
