Step 1 :Given the time intervals and the corresponding velocities, we can calculate the lower and upper estimates for the distance the car traveled after the brakes were applied.
Step 2 :The time intervals are \(0, 2, 4, 6\) seconds and the corresponding velocities are \(91, 46, 17, 0\) feet per second.
Step 3 :We calculate the differences in time, which are \(2, 2, 2\) seconds.
Step 4 :For the lower estimates, we take the minimum velocity for each time interval, which gives us \(92, 34, 0\) feet.
Step 5 :For the upper estimates, we take the maximum velocity for each time interval, which gives us \(182, 92, 34\) feet.
Step 6 :We sum up the lower estimates to get a total lower estimate of \(126\) feet.
Step 7 :We sum up the upper estimates to get a total upper estimate of \(308\) feet.
Step 8 :Thus, the lower estimate for the distance the car traveled after the brakes were applied is \(\boxed{126}\) feet and the upper estimate is \(\boxed{308}\) feet.
