Question 650148
{{{ W = k*(1/d) }}}
{{{ k }}} is called the constant of proportionality
given:
{{{ W = 220 }}} pounds
{{{ d = 3978 }}} mi
{{{ 220 = k*( 1/3978 ) }}}
{{{ k = 220*3978 }}}
{{{ k = 875160 }}}
---------------
{{{ W = 875160*(1/( 3978 + 400 )) }}}
{{{ W = 875160 / 4378 }}}
{{{ W = 199.8995 }}}
The astronaut weighs about 200 pounds
