Answer #1

2 km/hr * (2000 m/km) * (1 hr/60 min) = 33.333 m/min length
33.333 m/min * 0.4 m = 13.3332 m²/min

So the mower is mowing 13.3332 m²/min

From a google search, "The rectangular field is 160 feet (48.5 m) wide and 360 feet (109.1 m) in length (53.3 yards, 120 yards respectively), including the two 10 yard (9.2 m) end zones."

So a football field (including the end zones), has an area of 48.5 * 109.1 = 5,291.35 m²

Time require to mow would be 5291.35/13.3332 = 396.855 mins = 6.61425
