Time and Distance Questions for Banking and All Sarkari Examinations.
Time and Distance Questions for IBPS PO and SSC CGL
Basic Concepts :
1) When two bodies are moving around a circular track/ straight line track,
The relative motion of two bodies moving around in the same direction is taken as
= S1 – S2
Also, when bodies are moving in opposite direction, then relative speed
= S1 + S2
2) Trains are special case in the concept of speed, time and distance. The basic relation is same as,
Speed * time= distance.
a) When a train is crossing a moving object, the speed has to be taken as relative speed of the train with respect to the object.
b) The distance to be covered while crossing an object whenever a train crosses an object will be equal to
Length of train + Length of the object
c) Time taken by the train to cross a pole, man etc. by a train,
= Length of train /Speed of train.
3) A monkey or man tries to climb a pole ‘x’ m high. In ‘t’ time he climbs ‘y’ m but slips down ‘z’ m. How much time will be required by him to reach the top?
Reqd. time = [(ht. of pole – slipped distance)/(climbed distance – slipped distance)]*t
4) Suppose a car goes from A to B at an average speed S1 and then comes back from B to A an average speed of S2. If you have to find the average speed of the whole journey, then average speed is given by,
Average speed = 2S1 *S2/ (S1 +S2)
Average speed= 2* products of speeds/ sum of speeds.
From this section at least 2-3 questions will come for banking/ all sarkari exams.
