The distance traveled by a toy car can be modeled by D(t) = t3 − 3t2 + t − 3, where t > 3 represents time in seconds. If the car traveled for t − 3 seconds, identify the expression that represents the speed of the toy car.

The expression  that represents the speed of the toy car is .

Given that,

The distance traveled should be

Here t>3

Time taken by car = t -3 seconds

Now the expression should be

Step-by-step explanation:

We are given that

Distance traveled by a toy car

Where t>3

Time taken by car =t-3 seconds

We have to find the expression which represents the speed of the toy car.

We know that

Using the formula

Hence, the expression  which represents the speed of the toy car

all of them.
