Explanation:
First of all, we will find the area covered by the mower per unit time:
where,
v = speed of mower = 1 km/h = 1000 m/h
w = width of mower = 0.6 m
Therefore,
Now, the standard football ground has an area of:
A = 105 m x 68 m = 7140 m²
Therefore, The time required to mow the lawn will be:
<u>t = 11.9 h = 0.49 day</u>
