1-Researchers have determined that Titan (one of the Moon's of Saturn) has liquid water. If we could travel at 10 times the speed of sound, how long would it take us to fly roundtrip from the earth to Titan, if we explored Titan's ocean for 2 weeks before returning?

2- A man traveled at 55mph for the first half of his trip and 70mph on the return trip. If his total time round-trip is 45 hours, what is the total distance of the trip?
