Answer
Please see the work below.
Work Step by Step
The speed limit in the United States is given as
$v_{US}=65\frac{mi}{h}=65(\frac{0.4470\frac{m}{s}}{1\frac{mi}{h}})(\frac{\frac{1Km}{h}}{0.2778\frac{m}{s}})=105\frac{Km}{h}$
The speed limit in Canada is given as
$v_{Canada}=100\frac{Km}{h}$
So, we can conclude that the speed limit in the United States is greater.
