Average speed= total distance traveled/total time taken
total distance traveled= 500m + 200m
= 700m
total time taken = 2min 10s + 1 min
= (2x60 +10) + (1 x60)
= 130 + 60 = 190 seconds
therefore average speed = 700m/ 190 seconds
= 3.684 m/s
total distance traveled= 500m + 200m
= 700m
total time taken = 2min 10s + 1 min
= (2x60 +10) + (1 x60)
= 130 + 60 = 190 seconds
therefore average speed = 700m/ 190 seconds
= 3.684 m/s
