Dr.Ott can run a marathon (26.22 miles) in 2.925 hours. what is his average speed in miles per second?
Use dimensional analysis:
26.22mi/2.925hr * 1hr/3600s = 2.493x10^-3 mi/s
Notice how multiplying by 1hr/3600s allows you to cancel out hours in the denominator and replace it with seconds.
Well, it sounds like Dr. Ott is quite the speedy runner! Let's calculate his average speed in miles per second, shall we?
To do this, we'll need to take the total distance Dr. Ott runs (26.22 miles) and divide it by the time it takes him to complete the marathon (2.925 hours). But, since you're looking for his average speed in miles per second, we'll need to make a small conversion first.
Let's start by converting Dr. Ott's marathon time from hours to seconds. Since there are 60 minutes in an hour and 60 seconds in a minute, we can multiply his time by 60 twice.
2.925 hours * 60 minutes/hour * 60 seconds/minute = 10,530 seconds
Now that we have the total time in seconds, we can calculate the average speed:
Average speed = Total distance / Total time
Average speed = 26.22 miles / 10,530 seconds
And voila! Dr. Ott's average speed in miles per second is approximately 0.002485 miles per second. Now that's a lot of running, but you're not clowning around when it comes to math!
To calculate Dr. Ott's average speed in miles per second, we can use the following formula:
Average Speed = Total Distance / Total Time
First, convert the total time of 2.925 hours to seconds:
2.925 hours × 60 minutes/hour × 60 seconds/minute = 10,530 seconds
Next, divide the total distance of 26.22 miles by the total time in seconds:
Average Speed = 26.22 miles / 10,530 seconds
Calculating this division:
Average Speed ≈ 0.002485 miles/second
Therefore, Dr. Ott's average speed is approximately 0.002485 miles per second.
To find Dr. Ott's average speed in miles per second, we need to convert the time from hours to seconds, and then divide the distance by the converted time.
1 hour = 60 minutes
1 minute = 60 seconds
First, we convert the time:
2.925 hours x 60 minutes/hour x 60 seconds/minute = 10,530 seconds
Next, we divide the distance by the converted time:
Average speed = Distance / Time
Average speed = 26.22 miles / 10,530 seconds
To calculate Dr. Ott's average speed in miles per second, we divide 26.22 miles by 10,530 seconds:
Average speed = 0.0024865 miles/second
Therefore, Dr. Ott's average speed is approximately 0.0024865 miles per second.
