Answer:
A to B = 2000 m/s
C to D = 30,000m/s
Explanation:
A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s
C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s
a to b is 20m/s I'm in k12 and I got the same question but I don't know for c to d yet
A =0
B=200
T=10s
200 divided by 10 is 20m/s
and for the question at the bottom, the answer is c bc c to d is accelerating
