Answer: The two trucks will be 339.5 miles apart after 3.5 hours.
Explanation:
Let x =Time taken(in hours) by both trucks when they 339.5 miles apart.
Distance = Speed x Time
Distance traveled to North = 48x miles
Distance traveled to South = 49x miles
Total distance = 48x+49x = 97x miles = 339.5 miles [given]

Hence, the two trucks will be 339.5 miles apart after 3.5 hours.
1) Mercury; 2) Skylab; 3) Gemini; 4) Space Shuttle; 5) Apollo . The United States Agency that deals with space exploration and its programs is th NASA or National Aeronautics and Space Administration, with many successful missions, including puting the first man on the Moon (program Apollo).

The similarities, however, largely end there. The Chinese tried to simply ignore the Europeans. They were able to do this to some degree because the Europeans did not have anything they wanted. They were willing to take European silver in exchange for tea and otherwise leave the Europeans alone. This worked until around the time of the Opium Wars when the Europeans forced China to open itself more.
