Answer :
Final answer:
To find the velocity of the car, we calculate its average speed by dividing the total distance traveled by the total time taken. Using the given information, the velocity of the car is approximately 152.7 m/h.
Explanation:
To find the velocity of the car, we need to calculate its average speed. Average speed is calculated by dividing the total distance traveled by the total time taken. In this case, the car completes 4 laps, so it travels a distance of 4 times the length of the track. The total distance is therefore 4 * 218 m = 872 m.
Next, we need to convert the time given in seconds to hours, as we need to use the same units for time and speed. 23 seconds is equal to 23/3600 hours (since there are 3600 seconds in an hour).
Finally, we can calculate the average speed by dividing the total distance by the total time: 872 m / (23/3600) h = 152.7 m/h. Therefore, the velocity of the car is approximately 152.7 m/h.
