Answer:
The average speed of the ladybug from t = 1 second to t = 3 seconds is 4 m/s.
Step-by-step explanation:
The distance d that a ladybug travels over time t is given by :
Here,
d is in inches
t is in seconds
Let v is the speed of the ladybug. It is given by :
At t = 1 second, v = 2(1) -2 = 0
At t = 3 seconds, v = 2(3) -2 = 4 m/s
So, the average speed of the ladybug from t = 1 second to t = 3 seconds is 4 m/s.
