Hi there.
00:02
This is kind of a great question because it shows you how far you will travel in one foot if you're driving 95, or i'm sorry, if you're driving 65 miles per hour.
00:12
But it is a conversion problem.
00:15
So we're going to use dimensional analysis to convert from 65 miles per hour, which is what we are given to feet per second.
00:31
Right.
00:31
So let's go ahead and get started here.
00:35
So in the numerator, we need to convert miles to feet.
00:39
And the conversion for miles to feet is in one mile.
00:44
There are 5 ,280 feet.
00:51
I put mile in the denominator so that miles will cancel.
00:55
All right.
00:55
So now i have feet per hour, but i want feet per second...
