To answer this, we need more information, particularly a visual representation (the diagram) showing the distances or counts of blocks between each location: school, grocery store, and home.

Without the diagram, I can guide you on the approach to solve this problem:

1. Determine blocks from school to grocery store: Count the blocks along each route from school to the grocery store.
2. Determine blocks from grocery store to home: Count the blocks from the grocery store to her home.
3. Calculate total blocks walked: Add up the distances from school to grocery store and grocery store to home to get the total number of blocks.

If you upload the diagram or provide these distances directly, I can help complete the calculations accurately.

Follow-up Questions:

1. What is the exact distance (in blocks) between the grocery store and Jai's home?
2. Can you clarify whether Jai walks in a straight path or follows a specific route (with turns) between locations?
3. Would Jai's total distance change if she stopped at another location?
4. What if Jai took an alternative route? How would the number of blocks differ?
5. How might the geometry of the path (straight line vs. city grid) affect the answer?

Tip:

When calculating block distances in grid-based city layouts, add each segment's length separately along the horizontal and vertical lines.
