Remark
If you really take this question seriously, you will stop tailgating immediately. Being any less than 6 car lengths away from the car in front of you is dangerous even if you are paying attention, never mind if you are not.
Conversion
[tex]\dfrac{60 miles}{hour}*\dfrac{5280 feet}{1 mile}* \frac{1 hour}{3600 seconds}[/tex]
Now just multiply all the numerators together
60 * 6280 * 1 = 316800
And then multiply all the denominators together
1 * 1 * 3600 = 3600
Divide the numerators / denominators to get 316800/3600 = 88 feet / second
If you go 88 feet in 1 second you will go 88 * 4 feet in 4 seconds which is 352 which is about the length of a football field. It is an awfully long way to be inattentive.
