To find the average speed of the man, we need to calculate the total distance he ran and divide it by the total time taken.
The man ran 6 km to the east and 8 km to the west, which gives a total distance of 6 + 8 = 14 km.
Since he took 47 minutes to complete the exercise, we convert this time into hours by dividing it by 60: 47 minutes / 60 minutes = 0.7833 hours (rounded to four decimal places).
Now we can find the average speed by dividing the total distance by the total time: 14 km / 0.7833 hours = 17.87 km/hour.
Thus, the average speed of the man is approximately 17.87 km/hour.
a man runs for 6 km directly to the east until he gets at junction where he turns around and runs another 8km directly to the west .
what is the average of the man of decides to take 47 minutes to complete the exercise . give the answer in km
