Answer 1

I am pretty sure that when you travel the first mile in 10 minutes. The last mile takes you 15 minutes. This is an example of negative acceleration. I consider this to be correct because the second mile was slower. Hope you will agree with me. Regards!

Answer 2

Answer:

This is an example of negative acceleration.

You are riding your bike to the mall. You travel the first mile in 10 minutes. The last mile takes you 15 minutes.
