I think it is 72 minutes which is equal to 1hr12'

Nice.

Since we know that the distance to the store is the same forwards and backwards, we would make the distance the same.

Home = > 6mph = > store = > 4mph = > Home

Since one way is faster than the other we need to find the average between the both. As the average (5mph) would reveal the real length. As it would show the same distance for both sides.

12/5 is = 2.4

It's 2.4 miles backward and forwards.
