Givens.
• The speed is 100 mi/hr.
,• The time elapsed is 10 hr.
To find the distance traveled, use the constant motion formula.
[tex]d=vt[/tex]Where, v = 100 mi/hr and t = 10 hr.
[tex]\begin{gathered} d=100\cdot\frac{mi}{hr}\cdot10hr \\ d=1000mi \end{gathered}[/tex]Therefore, the train traveled 1000 miles.
