ANSWER
[tex]404.25km[/tex]EXPLANATION
To find the distance traveled, we have to apply the formula for speed:
[tex]\begin{gathered} speed=\frac{\text{distance}}{\text{time}} \\ distance=speed\cdot time \end{gathered}[/tex]Hence, the distance traveled by the truck is:
[tex]\begin{gathered} d=105\cdot3.85 \\ d=404.25km \end{gathered}[/tex]That is the answer.
