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
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.
