They both traveled for two hours, so you must multiply both speeds by 2 and then add those together to get your answer. You multiply by 2 because there speed is by miles per hour, and you have 2 hours. You add the two products together because you're trying to find the distance between the two cowboys.
So, here's the actual math:
20x2=40
15x2=30
40+30=70

There are 70 miles between the two cowboys two hours after they part. So, your answer is C.
