Question

If Sam types at a rate of $x$ words per minute, calculate how many minutes, in terms of $x$ will it take him to type $500$ words.

• A. $500x$
• B. $500-x$
• C. $500+x$
• D. $\frac{500}{x}$
• E. $\frac{x}{500}$

Answer 1

Answer: (D)

$\frac{500}{x}$

Sam types $x$ words in $1$ minute.

Time taken to type $1$ word is $\frac{1}{x}$.
Time taken to type $500$ words is $500\times \frac{1}{x}=\frac{500}{x}$.
