So if you're trying to find the other section of the 128 degree angle that isn't taken up by the 33 degree angle, or LHI, you just subtract 33 from 128. This is because you need to find the angle GHI without the part GHL, so just subtract that part away.
3,322.609847222222 mph. First covert miles to km. This distance is 239227.909 miles. then divide this by the number of hours which is number of days times 24. It took 3 days so it is 72 hours. After diving 239227.909/72 you get your answer of 3,322.609847222222 mph
