Answer 4

I know. Think about it: If he traveled 63.5 miles in 5 hours, and then the same amount of miles in half the time, his speed doubled. It took him a shorter amount of time to go the same distance. So, his speed doubled.

On Monday his speed was 63.5/5 = 12.7


& on Tuesday 63.5/2.5 = 25.4



It means his speed was \(\Large{\color{red}{DOUBLED}}\).
