please mark as brainliest and say thanks

Explanation:

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.
