The distance d (in inches) that a ladybug travels over time t

(in seconds) is given by the function d (t) =ť – 2t +2. Find

the average speed of the ladybug from ti = 1 second to

t2 = 3 seconds.

inches/second

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.
