Little Red Riding Hood goes to her aunt's

Classical Mechanics Level 2

Little Red Riding Hood loved travelling alone to her relatives' houses. Today she was going to meet her aunt at the other side of the river. She started off from her house. She was so excited that she kept increasing her velocity at constant rate. She was about to reach to her aunt's house, she saw the time, she had spent 1 minute. So, she started thinking, though she was still walking very fast, about how much acceleration has she attained assuming her final velocity as 60 m/s. Can you help her ? ( P.S.-She was a very fast runner, but this is not related to the solution of the question.).

1m/s sq. 10 m/s sq. 5 m/s sq. 2 m/s sq.

For constant acceleration, $a = \frac{\Delta v}{\Delta t} \\ = \frac{60\ m/s}{60\ s} \\ = 1\ m/s^2$
