Question 433080
The formula for this takes the form
{{{ d = k*(r^2) }}} where {{{k}}} is the
so-called "constant of proportionality"
You have to find {{{k}}}, so
{{{200 = k*(60^2)}}}
{{{200 = 3600k}}}
{{{ k = 1/18 }}}
Now, if the car travels {{{70}}} mi/hr,
{{{ d = (1/18)*(70^2) }}}
{{{ d = 4900 / 18 }}}
{{{ d = 272.22 }}} ft
