Time Speed & Distance Concepts for SSC And Railway Exam:
Quantitative Aptitude is an equally important section for SSC CGL, CHSL, MTS exams and has an even more fundamental importance in some other exams conducted by SSC. Generally, there are questions related to basic concepts and formulas of Time speed & Distance
Time Speed & Distance
a) Distance / Distance = Time × Speed (time + speed)
b) When Distance is constant / When distance is constant
When Time is constant / When time is stable
When speed in constant / When speed is stable
c) Average speed = (Total distance) / (Total time Taken) / Average speed = (Total distance) / (Total time taken) When Distance is equal / When distance is equal
