Answer:
(a) 16.777mi
(b)Yes, he was speeding
Explanation:
(a)
Let's do the proper operations in order to convert km to mi:
[tex]27km*\frac{1000m}{1km} *\frac{1mi}{1609.34m} =16.77706389mi[/tex]
We can conclude that the trip length in miles was:
[tex]d=16.77706389mi[/tex]
(b)
Let's calculate the speed of the man during the trip:
[tex]v=\frac{d}{t}[/tex]
But first, let's do the proper operations in order to convert min to h:
[tex]16min*\frac{1h}{60min} =2.666666667h[/tex]
Now, the speed is:
[tex]v=\frac{16.77706389mi}{2.666666667h} =62.91398959\frac{mi}{h}[/tex]
As we can see:
[tex]62.91398959\frac{mi}{h}>55\frac{mi}{h}[/tex]
So, we can conclude that the driver was speeding
