Answer:
v = 3 miles per hour
Step-by-step explanation:
It is given that,
Distance covered by the person, [tex]d=15\dfrac{3}{4}\ miles=15.75\ miles[/tex]
Time taken by the person, [tex]t=5\dfrac{1}{4}\ hours=5.25\ hours[/tex]
Let v is the speed of the person. It is defined as total distance covered divided by total time taken. Mathematically, it is given by :
[tex]v=\dfrac{d}{t}[/tex]
[tex]v=\dfrac{15.75\ miles}{5.25\ hours}[/tex]
v = 3 miles/hour
So, the average rate of speed is 3 miles/hour. Hence, this is the required solution.
