Since None of the Lawn Mowers, ===> Operates for Less than 900 Minutes

Lowest Possible Length: =====> 900 Minutes

Greatest Possible Length: ========> 990

Average Speed ====> 930 (L1 + L2 + L3) / 3 = 930

Set to Lowest Possible: L1 and L2 ======> 900 Minutes Each


Solve: L1 + L2 + L3 ====> (Lawnmowers 1, 2, 3):

( 900 + 900 + L3) / 3 = 930 L3 ====> 990.

Greatest Possible Length of Time; Answer ====> 990 minutes.
