Through a little bit of math, I have found out that running a race with twice the speed for half the race and half the speed for the other half is much slower than if you ran at the normal speed the whole time.

"Half the race" is too ambiguous to make a conclusion on the accuracy of this statement. Half of the duration of the race? Half of the distance of the race?

Indeed. Interesting observation. At first glance it intuitively seems wrong but the algebra tells that you'd take 1.25x the time instead. Consider the second half of the race - running at half the speed already takes you the same time as running the full length at normal speed.

To the quote below: "Half the race" means "half the distance of the race", not "half of the total time you ran".

This isn't true. If you ran at 2 miles an hour normally for say 2hours, if you go twice the speed for one hour (4 miles) plus half the speed for one hour (1 miles) that's 5miles, if you ran just normally for two hours it's 4 miles, your maths is wrong.

Why is it that I can't see my own quotes over the website when I'm taking a typing test?
