Cortney is downloading some files to her computer. Her internet speed is 2 megabits per minute. If she can download the files one at a time and the files she is downloading have the size of 80 megabits, 90 megabits, and 70 megabits. How many hours will it take for her to download all of it? Think carefully first, then make a decision:
The first file will take 80 / 2 = 40 minutes to download. The second file will take 90 / 2 = 45 minutes to download. And the third file will take 70 / 2 = 35 minutes to download. So, it will take 40 + 45 + 35 = 120 minutes for all the files to download. Therefore, the total hours she will have to spend to download all the files is 120 / 60 = 2 hours. So, the answer is 2.
