How would decreasing the time it takes you to run a certain distance affect your speed

Lets say you have a distance x = 1 mile. If you run that 1 mile and it takes you 10 minutes, you had a speed of 0.1 miles per minute. Then you run the mile again and it only takes you 8 minutes this time. Now your speed is 0.125 miles per minute. You speed has increased from 0.1 to 0.125 miles per minute. If you want to decrease the time it takes to travel across a distance, then you must increase your speed.

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.
