Given:

The vertical height is 30ft.

The angle of elevation is 30 degrees.

To find:

The distance travelled by the person from bottom to top of the escalator.

Explanation:

Let x be the slant distance.

Since it is a right triangle.

Using the trigonometric ratio formula,

[tex]\begin{gathered} \sin\theta=\frac{Opp}{Hyp} \\ \sin30^{\circ}=\frac{30}{x} \\ \frac{1}{2}=\frac{30}{x} \\ x=30\times2 \\ x=60ft \end{gathered}[/tex]

Therefore, the distance travelled by the person from the bottom to the top of the escalator is 60ft.

Final answer:

The distance travelled by the person from bottom to top of the escalator is 60ft.
