Answer:
[tex]\boxed {\tt 3.4 \ mi/hr}[/tex]
Explanation:
To find speed, divide the distance by the time, or use the following formula.
[tex]s=\frac{d}{t}[/tex]
The distance is 1.7 miles.
The time is 0.5 hours.
[tex]d= 1.7 \ mi \\t= 0.5 \ hr[/tex]
Substitute the values into the formula.
[tex]s=\frac{1.7 \ mi}{0.5 \ hr}[/tex]
Divide.
[tex]s= 3.4 \ mi/hr[/tex]
The speed of the horse is 3.4 miles per hour.
