<PRE><B>Question 1049228</B>
d = r*t so r = d/t
d(1) = 2.6667(1)^2
d(1) = 2.6667
r = 2.6667/1 = 2.6667 is the speed, and in this case, where t=1, it is also the distance traveled in 1 second
-------------------
d(4) = 2.6667(4)^2
d(4) = 2.6667*16 = 42.6672 is the distance traveled in 4 seconds
r = 42.6672/4 = 10.6668 is the speed per second
