question 15 of 15
what is the order of magnitude for the speed limit of driving on an interstate in the united states?

Explanation:

Step1: Know the speed limit

The speed limit on an interstate in the United States is typically around \(60 - 80\) miles per hour. Let's take \(70\) miles per hour as an example.

Step2: Calculate the order of magnitude

We use the formula for order of magnitude. If \(x\) is a number, the order of magnitude is \(n\) such that \(10^{n}\leq x<10^{n + 1}\). For \(x = 70\), we can write \(70=7\times10^{1}\). Since \(10^{1}\leq70<10^{2}\), the order of magnitude is \(1\).

Answer:

\(1\)
