A football plane has dimensions 112.5 long and 64m wide. Karin grasses on the plane along a motor-powered lawnmower that has the cutting edge 1m karin runs at a speed of 1.5m per second .has long time take it for her to cut the whole plan if she cut effectively possible

Cutting along the longest dimension of the field, it will take her  112.5 / 1.5  =  75 seconds = 1 + 1/4 min  = 5/4 min to cut a 1 m wide swath

And she must do this 64 times to cut the entire field.....so

64 * (5/4)   min  =

64/4  *  5  =

16 * 5  =

80 min  total
