Need help with 6 I don’t get it

Answer:
I think the answer may be C or 15
Step-by-step explanation:
Every square is a mile, I found out because there are 13 miles to get to school and it is 13 squares to get to the destination. I counted 15 squares from home to the store (I think)
If I am wrong it could be D, nonetheless its not A or B
Step-by-step explanation:
I think that should be 13 because if you draw a line from home to school it indicates that home to school and grocery store to school it's an isosceles triangle because two opposite sides of the home to school and the school to the grocery store are equal
