Question

A car moving at a constant speed passed a timing device at t=0. After 8 seconds, the car has traveled 872 ft. Write a linear function rule to model the distance in feet d the

car has traveled any number of seconds t after passing the timing device.

The linear function rule is W= ?

Answer 1

Explanation:

We can use the formula for the distance traveled by an object moving at a constant speed, which is:

distance = speed x time

In this case, the car is moving at a constant speed, so we can use this formula to find the linear function rule for the distance the car has traveled any number of seconds t after passing the timing device.

We know that the car traveled 872 feet after 8 seconds, so we can use this information to find the speed of the car:

speed = distance / time = 872 ft / 8 s = 109 ft/s

Now we can use this speed to write the linear function rule:

distance = speed x timed = 109t

So the linear function rule to model the distance in feet d the car has traveled any number of seconds t after passing the timing device is:

d = 109t
