Answer: 5 minutes(not sure)
Explanation:
She first left her house and went to the shops which approximately says in the graph that she went there at 2 time elapsed(minutes) and then left a 5 when you take that away it gives u 3 minutes
So to find out how long it took her to come out of the bank she arrived at 7 time elapsed (minutes) and then left at 12, you do 12-7=5
Therefore i think the answer is 5 minutes
