Question

Bill has ridden 68 miles of a bike course. The course is 85 miles long what percentage of the course has bill ridden so far

Answer 1

We can state this question as a rule of three, that is,

$\begin{gathered} 85\text{ miles ------ 100 \%} \\ 65\text{ miles ------- x} \end{gathered}$

then, x is given as

$\begin{gathered} x=\frac{(65\text{ miles) (100 \%)}}{\text{85 miles}} \\ \end{gathered}$

which gives

$\begin{gathered} x=\frac{6500}{85}\text{ \%} \\ x=76.47\text{ \%} \end{gathered}$

Then, the answer is 76.47 %

We know that the total miles is 85 miles. So we can find the ratio of traveled miles to total miles, which is

$\frac{65}{85}=0.7647$

This means that 65 miles represents 0.7647 of 85 miles. In percentaje, this corresponds to 7
