Answer:
None of the answer choices show the correct answer.
The actual answer is 140 miles.
Step-by-step explanation:
Since Cooper drove 60 miles per hour for 2 hours, that means that he drove 120 miles for the first 2 hours.
60 * 2 = 120
Cooper then drove for another 30 minutes at a speed of 40 miles per hour.
30 minutes is half of and hour so we need to divide the 40 miles by 2.
40 / 2 = 20
Now we just have to add them together.
120 + 20 = 140
So the answer is 140 miles.
Hope this helps! :)
