The correct equation to calculate average speed is
|
|
total distance/total time
|
|
|
time/distance
|
|
|
distance x time
|
|
|
distance/time
|
Explanation:
Detailed explanation-1: -Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr. Hence the correct option here is C) 48 km/hr. So to find the average speed never use the formula of the averages but try to find the total distance covered and the total time taken.
