You can put this solution on YOUR website!

if a car travel %283%2F8%29 of a mile in 17.564 seconds, then
%283%2F8%29%2F17.564=0.375%2F17.564=0.0214%28mil%2Fs%29 (miles in one second)
since 1second=0.0002778hours if a car travel 0.0214%28mil%2Fs%29 , then
speed of the car will be %280.0214%2F0.0002778%29%28mil%2Fh%29=77.04%28mil%2Fh%29
