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]

\Rightarrow\ x=\dfrac{339.5}{97}\\\\\Rightarrow\ x=3.5

Hence, the two trucks will be 339.5 miles apart after 3.5 hours.
