If I ran 19.22 seconds to run 100 meters how long would it take to run 60 meters?

Question

If it took me 19.22 seconds to run 100 meters how long would it take to run 60 meters?

Answer 1

My solution:

 

First, find out how fast you ran the first 100 meters.  Take 100 meters divided by 19.22 seconds to get your meters/second of 5.2 m/s.

 

Now, use that 5.2 m/s speed to find out how long it would take you to run 60 meters (assuming the same speed and ignoring acceleration, fatigue, or other outlying factors).  Take 60 meters divided by 5.2 m/s to get the answer of 11.53 seconds.
