Answer:

A. 140

Step-by-step explanation:

3 hours converts to 180 minutes, so 180-40=140, therefore A is correct.

140
Explanation: there are 60 minutes in an hour so we know she has at least two full hours left. If we multiply 60 by two and then add the remaining 20 minutes in the first hour from the 40 already used, we get 140. Hope this helped!
