You can put this solution on YOUR website! My car goes 0 to 60 in 7.9 seconds. How far did my car travel once it reached 53mph?
==================
60 mi/hr = 88 ft/sec
Assuming uniform acceleration:
a = v/t = 88/7.9 =~ 11.139 ft/sec/sec
-----
53 mi/hr =~ 53*88/60 = 77.733 ft/sec
t = v/a =~ 6.978 seconds to reach 53 mi/hr
---
s = at^2/2 = 271.22 feet
