Answer:

a)200 mph

b)80 mph

c)-40 mph

d)97 mph

e)56 mph

(note: i rounded the answer for d, it was a repeating decimal)

Step-by-step explanation:

a) 3s-0s=3s 600m-0m=600m 600m/3s=200m/s

and it is the same for the rest. Use the explanation for A as a example.

So you take the final variable or speed and subtract it by the starting, then divide that by the time elapsed. Hope this helped!
