An empty plane fit waka 600 MPH, but each passenger make am waka 2 MPH slower. Wetin be their average speed?``` <response>: The first plane dey go 100 MPH slower pass empty because 50 x 2 = 100
The first plane dey go 500 MPH because 600 - 100 = 500
The second plane dey go 120 MPH slower because 60 x 2 = 120
The second plane dey go 480 because 600 - 120 = 480
The third plane dey go 80 MPH slower because 40 x 2 = 80
The third plane dey go 520 MPH because 600 - 80 = 520
The total speed na 1500 because 500 + 480 + 520 = 1500
Their average speed na 500 because 1500 / 3 = 500

The answer go be 500.
