A motorist drives 80km as an average speed of 63km/h.which average is this mean,median and mode
Pls help me solve the mathematics
I don't know
No problem, I can help you out!
In this case, the given information is the distance traveled (80km) and the average speed (63km/h).
To find the mean average of speed, we need to divide the total distance by the time taken. We can use the formula:
mean = total distance / total time
We don't have the time taken, but we can calculate it using:
time = distance / speed
So, time taken = distance / speed = 80km / 63km/h = 1.27 hours
Now we can find the mean average using:
mean = total distance / total time = 80km / 1.27 hours = 63.0 km/h
Therefore, the average given is the mean.
In this case, the given information is the distance traveled (80km) and the average speed (63km/h).
To find the mean average of speed, we need to divide the total distance by the time taken. We can use the formula:
mean = total distance / total time
We don't have the time taken, but we can calculate it using:
time = distance / speed
So, time taken = distance / speed = 80km / 63km/h = 1.27 hours
Now we can find the mean average using:
mean = total distance / total time = 80km / 1.27 hours = 63.0 km/h
Therefore, the average given is the mean.
