Question

the graph shows the motion of a person on a moving walkway in an airport. choose quantities to complete the statements. in 10 seconds, a person on the walkway moves 20 meters. in 30 seconds 40 seconds, a person on the walkway moves 60 meters.

Explanation:

Step1: Find the speed

Since in 10 seconds, a person moves 20 meters, the speed $v=\frac{20}{10}=2$ m/s.

Step2: Calculate the time for 60 - meter movement

Using the formula $t = \frac{d}{v}$, where $d = 60$m and $v = 2$m/s. So $t=\frac{60}{2}=30$ s.

Answer:

30 seconds
