Answer:
• 90 miles per hour.
,• 360 miles
Explanation:
After 1 hour, he has 270 miles left to travel.
After 2 hours, he has 180 miles remaining.
To determine the speed of the train, we find the rate of change.
[tex]\begin{gathered} \text{Slope},m=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}} \\ =\frac{270-180}{1-2} \\ =\frac{90}{-1} \\ =-90\text{ miles per hour} \end{gathered}[/tex]The speed of the train is 90 miles per hour.
If the train travels 90 miles per hour, and after 1 hour, he has 270 miles to travel:
The distance of the train is:
[tex]\begin{gathered} =270+90 \\ =360\text{ miles} \end{gathered}[/tex]
