An automobile travels for 90 minutes along a highway. The graph shows the progress of the automobile, with its start point designated as distance = 0 km.



What is the automobile's average speed as it travels from a distance of 5 km to a distance of 15 km along the highway?

Respuesta :

Answer:

V = 11.11 m/s

Explanation:

From the graph,

The time corresponds to the distance 5 Km is, t₁ = 15 min

The time corresponds to the distance 15 Km is, t₂ = 30 min

The distance traveled by the automobile is, d = 15 Km - 5 Km

                                                                             = 10 Km

                                                                             = 10000 m

The period of travel is given by the time interval t = t₂ - t₁

                                                                                   = 30 - 15

                                                                                    = 15 min

                                                                                     = 900 s

The average velocity of the automobile is,

                                          V = d / t

                                             = 10000 / 900

                                             = 11.11 m/s

Hence, the average velocity of the automobile is, v = 11.11 m/s
