HI Emma! Without context, it is somewhat hard to give you an exact answer, but generally speaking, it means "When will it be ready?" For example, you take your car into the shop for repair, and the mechanic tells you that the rotor on your brake on your right front tire is worn, which resulted in the "pulling" motion you had felt. You would then ask about the cost and then how long it will take to repair it. So, that time period [from broken to fixed] is the turn-around time. While usually applied to the repair of things, through analogy, it could be applied to any similar situation where you need to wait for your property, your money, etc., to be returned to you. I hope this helps you, but feel free to contact me if you still have any questions. J.
