Answer:

x = 9 cm

create proportional equation:

$\sf \dfrac{9}{3x-20} = \dfrac{72+9}{3x-20+56}$

$\sf \dfrac{9}{3x-20} = \dfrac{81}{3x+36}$

$\sf 9(3x+36) = 81(3x-20)$

$\sf 27x+324 = 243x-1620$

$\sf 27x-243x=-1620-324$

$\sf -216x=-1944$

$\sf x = 9$

If 6.45 is supposed to be miles
6.45 miles = 10380.269 metres
10380.269+15+500=10,895.269
but that is only if the 6.45 is in miles
