Answer 1

Answer:

c) 2.4 m/s

Explanation:

Total distance travelled = 10m + 20m + 30m

                                        = 60m

Total time taken = 5 + 10 + 10

                            = 25s

Average speed = $\frac{Distance}{Time}$

                          = $\frac{60}{25}$

                          = 2.4 m/s

Answer 2

ANSWER: 2.4 m/s

average speed= total distance travelled / time taken

= 10+20+30 / 10+10+5

= 60 / 25

= 2.4 m/s
