Norma-Jean [14]

Answer:

10m/s,15m/s,20m/s,5m/s

Step-by-step explanation:

Speed = distance / time

Speed = 10m/s

b) distance = 300m , time = 20s

Speed = distance / time

Speed = 300m/20s

Speed = 15m/s

c) distance = 700m , time = 35s

Speed = distance / time

Speed = 700m/35s

Speed = 20m/s

d) distance = 1000m , time = 200s

Speed = distance / time

Speed = 1000m/200s

Speed = 5m/s
