The InstantRide Management team considers creating a new team for Car Maintenance. The new team needs to find/list the cars that are used more than average with the usage count. Collect the information of all rides and consolidate over the Car IDs. You need to create a three level SQL statement. Firstly, you need to COUNT the number of rows in TRAVELS and GROUP BY the CAR ID field. Then you need to calculate the AVG of the data to find the average usage of the cars. Finally, you need to return CAR_ID and the TRAVELS count (as the Usages column) filtered to only values greater than the calculated average. Task
