How many minutes to walk 7 blocks?

It depends on the length of the blocks, how fast you walk and the amount of time spent in stores and street corners waiting for lights to change.

ex.

I walked 7 blocks in 20 minutes (not counting lights or shops). I stopped at 2 lights for 2 minutes each. So that brings me to 24 min. I stopped at a store for 4 minutes. It took me 28 min to walk 7 blocks.
