You can
put this solution on YOUR website!Is the 804 meters or miles? I assume it's miles.
If not, just do a conversion.
The key is: how much of a head start does your son have?
sec =
hrs
In 5 seconds at 6 mi/hr, he goes
mi
mi head start
Now you start a stopwatch when you are released.
Your equation is:
(1)
(t is in hours)
Your Son's equation is:
(2)
( you both will have the same t now)
and
(3)
You have 3 equations and 3 unknowns, so it's solvable
Substitute (1) and (2) in (3)
(3)
(3)
hrs
Now convert to seconds:
hrs x
sec/hr =
sec
It will take you 30 sec to pass your son
------------------------------
You will have gone
mi
That is
ft
