Question

a particular truck in a transportation fleet was driven 194,070 miles last year versus 329,919 miles this year . by what percent did the annual distance driven increase

Answer 1

We take as the 100% the 194070 miles from last year. Then, we apply a rule of three:

`\begin{gathered} 194070\rightarrow100\text{ \%} \\ 329919\rightarrow x\text{ \%} \\ \Rightarrow x=(329919\cdot100)/(194070)=(32991900)/(194070)=170 \\ x=170\text{ \%} \end{gathered}`

Since 329,919 is the 170% of last year's miles, then the increase was of 70%
