Speed,distance,time

Question 1

Calculating speed

Answer 1

•speed (m/s) = change in distance (m)
                           ——————————
                             Time taken (s)

Question 2

Average speed

Answer 2

Average
Speed (m/s) =total distance traveled(m)
————————————
Total time taken (s)

                                   Or 

Distance
Travelled(m) = average X Time taken (s)
Speed(m/s)
