Answer:
Speed of Victoria, [tex]v=32\dfrac{1}{4}\ miles/hour[/tex]
Step-by-step explanation:
It is given that,
Distance covered by Victoria, [tex]d=21\dfrac{1}{2}\ miles=\dfrac{43}{2}\ miles[/tex]
Time taken, [tex]t=\dfrac{2}{3}\ hour[/tex]
Speed (v) of Victoria is given by total distance divided by total time taken. It is given by :
[tex]v=\dfrac{d}{t}[/tex]
[tex]v=\dfrac{\dfrac{43}{2}\ miles}{\dfrac{2}{3}\ hour}[/tex]
[tex]v=\dfrac{129}{4}\ miles/hour[/tex]
or
[tex]v=32\dfrac{1}{4}\ miles/hour[/tex]
So, the speed of Victoria is [tex]32\dfrac{1}{4}\ miles/hour[/tex]. Hence, this is the required solution.
