To determine the total number of tires needed for a fleet of 622 vehicles, you would multiply the number of vehicles by the number of tires each vehicle requires. Assuming each vehicle has 4 tires, the calculation would be 622 vehicles x 4 tires per vehicle 2,488 tires needed for the fleet.
To determine the total number of tires needed for a fleet of 700 vehicles, you would multiply the number of vehicles by the number of tires each vehicle requires. Assuming each vehicle has 4 tires, the calculation would be 700 vehicles x 4 tires per vehicle 2800 tires needed for the fleet.
