It takes Grayson 2 minutes to walk each block on the grid. How long will it take Grayson to walk from the bakery to the hospital, and then from the hospital to the flower shop?

Since we don't know the exact location of each place on the grid, we cannot determine the exact number of blocks Grayson needs to walk to go from the bakery to the hospital, and then from the hospital to the flower shop. Therefore, we cannot determine the total time it will take him to make both trips.
