What is its average speed for the entire trip?įor such problems, don’t fall in the trap of taking an average of the two given speeds even in cases where the times t 1 and t 2 are the same. Let us understand this using a problem – Say, a car travels at S 1 mph on a trip in t 1 time and at S 2 mph on return trip in t 2 time. d n if their corresponding different time intervals t 1, t 2,….t n are given.

The formula for Average Speed helps you to calculate the average speed of different distances d 1, d 2…. Then how to calculate it? Let’s take a look! Understanding Average Speed – SSC & Railways ExamsĪverage speed is a measure of the distance traveled in a given period of time, it is sometimes referred to as the distance per time ratio. The average speed of an object basically tells you the (average) rate at which it covers a certain distance while its speed at different times is variable. We all know the formula for average which is as follows –Īverage Speed is not equal to the average of all the speeds.

Calculate the average speed
