Question 1170675
I learned in driver's training that 60 mph is 88 ft/sec.  It is useful to know, because after that for any mph, one may calculate ft/sec.
88 ft/sec*4.9sec=431.2 feet.

If you want to prove the above
60 mi/hr*1hr/3600 sec*5280 ft/1 mile=88 ft/sec

-
4.9 sec* 1 hour/3600 sec=0.001361111hr*5280 ft/1mile*60 mi/1 hour for same answer.
