Time, Speed & Distance is one of the most important topics in quantitative aptitude section in various SSC and Banking exams. generally there are 4-5 questions asked on this topic in various competitive exams. by preparing for this topic, students can score good marks in Aptitude section for various competitive exams. this course includes quality notes with tips and tricks to help students solve these type of questions in no time.
Relationship Between Speed, Time & Distance
Speed = Distance / Time
We can deduce the following from this formula:-
– When time is constant, distance covered is directly proportional to the speed.
– When distance is the same, speed is inversely proportional to time.
Average Speed = Total Distance Traveled / Total Time Taken
– Remember that average speed is NOT the arithmetic mean of the speeds.
– Also, average speed can never be double or more than double of any of the original speeds.
When two objects with speed S1 and S2 respectively and they are traveling in:
– Same direction, the relative speed (S’) is the difference of the individual speeds
S’ = S1 – S2
– Opposite direction, the relative speed (S’) is the sum of the individual speeds
S’ = S1 + S2
