No the time it takes to travel a distance is an easy formula. It is derived from the formula for speed, where speed is equal to distance divided by time. To calculate In the video, he draws a curved line to display the relationship, and his is wrong. Displaying that formula as a graph to display how long it takes to travel a known distance looks like this:
EDIT to add: The below graph is not a good representation of my point. You can ignore it, but I am leaving it here as a monument to my error. My point still stands: his claim that driving faster doesn’t make a difference is still false. If you go 70 mph versus 60, you are travelling about 16% faster, so you will get there 16% sooner. If you are travelling 20mph instead of 15mph, you are travelling 33% faster, so you will get there 33% sooner.
He is saying that it doesn’t pay to drive faster, which is false. The benefit to driving faster is directly proportional to the increase in speed.

Note that the graph is a straight line. He is either stupid or deliberately lying. The difference between 5 mph and 10 mph will get you there in half the time, because you are travelling twice as fast. The reason why you only save a few seconds when you drive at 65 versus 60 mph is that 65 is not even ten percent faster than 60.
