A cyclist is travelling with a speed of $\"\"$ .

At the same and same starting point an inline skater follows the cyclists path.

A inline skater is travelling with a speed of $\"\"$ . \ \

Draw a diagram

$\"\"$

Let time is $\"\"$ both are travells same time.

Where $\"\"$ is number of hours untill they travelling distance.

$\"\"$

Find time $\"\"$ at which the cyclist and the skater will be $\"\"$ apart. \ \

Distance formula : $\"\"$ .

Let time $\"\"$ be number of hours at which they are $\"\"$ apart.

Make a table:

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

$\"\"$

Solve equation.

Distance travelled by an cyclist minus Distance travelled by an inline skater equals $\"\"$ .

$\"\"$ .

$\"\"$ (Original equation)

$\"\"$ (Simplify)

$\"\"$ (Divide each side by $\"\"$ )

$\"\"$ (Simplify)

Therefore, they are travelling $\"\"$ apart after $\"\"$ . $\"\"$

They are travelling $\"\"$ apart after $\"\"$ .
