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 30 meters in, a person on the walkway moves 60 meters.

Explanation:

Step1: Calculate the speed

The person moves 30 meters in 10 seconds. Speed $v=\frac{d}{t}=\frac{30}{10} = 3$ m/s.

Step2: Find the time for 60 - meter movement

We know $v = 3$ m/s and $d = 60$ m. Using $t=\frac{d}{v}$, we get $t=\frac{60}{3}=20$ s.

Answer:

20 seconds
