The essential part of the Hot Wheels speed booster is made of two fast spinning, rubberized disks of radius r=0.048 m each. The toy car entering the booster is in direct contact with both wheels, which send it away after brief encounter with it.

When the speed booster is set up horizontally at the edge of a table (h=0.92 m) it sends the car in the projectile motion so that it lands at horizontal distance of x=1.68 m away from the edge of the table.
Use this information to find the angular velocity of the spinning disks in the booster.
Give your answer in rpm -- revolutions per minute
