At 9:00 am you start to walk and at 10:30 am you are 7.25km from your starting point. Determine your average speed in meters per second
To determine the average speed in meters per second, we need to convert the distance covered from kilometers to meters and the time from hours to seconds.
Distance covered in meters = 7.25 km * 1000 m/km = 7250 m
Time taken in seconds = (10:30 am - 9:00 am) * 60 minutes/hour * 60 seconds/minute = 1.5 hours * 60 minutes/hour * 60 seconds/minute = 5400 seconds
Average speed in meters per second = Distance covered in meters / Time taken in seconds
= 7250 m / 5400 s
= 1.3426 m/s (rounded to four decimal places)
Therefore, your average speed is approximately 1.3426 meters per second.
