Page 124 of your reading material you are shown a calcuation to determine a car's final speed after accelerating for 4 seconds what would be the speend after 3 seconds?

To determine the car's speed after 3 seconds, you would need to know the initial speed and the acceleration. Using the formula ( \text{final speed} = \text{initial speed} + (\text{acceleration} \times \text{time}) ), you can substitute the time value with 3 seconds instead of 4. Without specific values for initial speed and acceleration provided in the reading material, I can't calculate the exact speed.
