Let they meet after second car travels for x hours'
let v be the speed  of second car and V be speed of first car.
Then time taken by first car=x+2
V(x+2)=vx (distance covered is same.)
\frac{v}{V} = \frac{x+2}{x} 
subtract 1 from both sides
 \frac{v-V}{V} = \frac{2}{x} 
v-V= \frac{2V}{x}

Divid to get the other side :) so if the doll house is 1/12 of the queen size bed you divid each side by 12 see. 4800/80=60. 80/12=6.6667.... so 60/12=5. so then 5x6 1/3. hope this helps you ... goood luck! :)
