Answer with explanation:
Speed
[tex]=\frac{\text{Distance traveled}}{\text{Time taken}}[/tex]
When you will observe the graph
Time is represented on X axis
And , Distance traveled is represented on Y axis.
In 5 hours ,Henry travels a distance of 300 miles.
So, in 1 hour distance traveled by Henry
[tex]=\frac{300}{5}\\\\=60[/tex] miles
So, Speed of Henry
[tex]=60 \frac{miles}{hour}[/tex]
Speed can be calculated by this method also
[tex]=\frac{\text{Difference in two y values lying on the straight line}}{\text{Corresponding x values}}\\\\=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{300-0}{5-0}\\\\=60 \frac{miles}{hour}[/tex]
Option D: 60 miles per hour
