When Mr. Cansetti reaches the Police Station,
he has walked 7.5 blocks from his home,
and has passed the Post Office.
The Post office is 3.5 blocks behind him,
so the Post office is {{{7.5-3.5}}}{{{"="}}}{{{"4.0"}}} blocks from Mr. Cansetti's home.
So, when Mr Cansetti had reached the Post office, he had walked 4.0 blocks.
Since the Store is {{{"6.0"}}} blocks from the Post Office,
after walking 4.0 blocks and reaching the Post office,
Mr. Cansetti had to walk 6.0 more blocks to get to the store, for a total of
{{{"4.0 + 6.0 ="}}}{{{highlight(10)}}} blocks.
