Given:
Speed at which Sameer went on his boke from Delhi to Gurgaon (v1)
= 60 km/hr
Speed at which Sameer came back from Gurgaon to Delhi (v2)
= 40 km/hr
To Find:
The Average Speed For His Entire Journey.
Calculating:
The Formula That We Use To Calculate Average Speed:
= 2 x v1 x v2/ v1 + v2
Substituting all the values known to us in this formula we get:
= 2 x 60 x 40 / 60 + 40
= 120 x 40 / 100
= 4800 / 100
= 48 km/hr
Therefore, the average speed of Sameer's bike during the journey was
48 km/hr.
