Question

Define average speed and write its mathematical formula

Answer 1

Explanation:

The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance. To calculate the average speed of an object, we do not care about fluctuations in its speed

Answer 2

$\huge \underline \bold \green{Answer}$

Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. Speed is how fast something is going at a particular moment. Average speed measures the average rate of speed over the extent of a trip.

Time = Distance / speed = 1800/40 = 45 hours. Thus we can find the average speed as: Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr.
