Question

If Marisa drove $n$ miles in $t$ hours, which of the following represents her average speed, in miles per hour?

• A. $\frac{n}{t}$
• B. $\frac{t}{n}$
• C. $\frac{1}{n}t$
• D. $nt$
• E. $n^{2}t$

Answer 1

The correct option is A $\frac{n}{t}$

Formula:- Distance $=$ Speed $\times$ Time

Distance $=n$ miles

Time $=t$ hours

Therefore Speed $=$ Distance$÷$ Time

Speed $=n$ $÷$ $t$ miles per hour
