Answer:a) Distance= 240m. b) Displacement= 90m. c) Average Speed= 5[tex]ms^{-1}[/tex]. d) Average Velocity= 1.875 [tex]ms^{-1}[/tex]

Explanation:

a) Distance ➤ (80+50+70+40) m. ➤ Distance= 240m.

b) Displacement ➤ (50+40)m. ➤ Displacement= 90m

c) Average Speed ➤ Total distance travelled/total time taken

                              ➤ 240/48

                              ➤ 5 [tex]ms^{-1}[/tex]

d) Average Velocity ➤ Total displacement/total time taken

                                 ➤ 90/48

                                 ➤ 1.875 [tex]ms^{-1}[/tex]
