Question 1083138
A well-known right triangle is the 3-4-5 triangle
( because {{{ 3^2 + 4^2 = 5^2 }}} )
This is also a 3-4-5 triangle if the sides are in
that same proportion.
Let {{{ c }}} = distance from home
{{{ (1/7)*21 = 3 }}}
{{{ (1/7)*28 = 4 }}}
{{{ (1/7)*c = 5 }}}
{{{ c = 35 }}}
The motorcycle is 35 miles from home
