Question

The posted speed limit is 45 per hour. Choose all the metric measures that are faster than 45 miles per hour.

Answer 1

C. 86.4 km per hour

D. 91 km per hour

E. 112.3 km per hour

Step-by-step explanation:

From the table, we can see that 1 mile is equal to 1.6km.

So let's go ahead and determine how many kilometers is equivalent to 45 miles;

`\begin{gathered} 1\text{ mi }\rightarrow\text{ 1.61 km} \\ 45\text{ mil }\rightarrow\text{ x} \\ x=45*1.61\text{ = 72.45km} \end{gathered}`

Therefore, 45 miles per hour is equivalent to 72.45 kilometers per hour, so 86.4 km per hour, 91 km per hour, and 112.3 km per hour are all faster than 45 miles per hour (72.45 km per hour)
