Speed of the car during 1st half time (s1) = 40 km/ hr
Speed of the car during 2nd half time (s2) = 60 km/ hr
We know that,
Since Average speed (sa ) = s1 + s2 / 2,
Therefore Average speed of the car = 40 + 60 / 2
= 100 / 2
= 50 km/ hr
:. The average speed of the car is 50 km
Speed of the car during 2nd half time (s2) = 60 km/ hr
We know that,
Since Average speed (sa ) = s1 + s2 / 2,
Therefore Average speed of the car = 40 + 60 / 2
= 100 / 2
= 50 km/ hr
:. The average speed of the car is 50 km
