Answer: It would take 40 minutes to mow a lawn with a mower containing 12-inch wide blades.
Step-by-step explanation:
If the time taken by 14 inches wide is one hour then the blade of 12 inches wide will take 1 hour 17 minutes to mow a lawn.
The width of something is the measurement of one side of a body. It is generally less than length of that body or shape.
We have been given time of 1 hour if blade is 14 inches wide and we have to calculate time taken by 12 inches wide blade:
It will be as 14/12* 1 hour
=14/12
=1.167
=1.17 hour
Hence the time taken by the blade of 12 inches wide will be 1 hour and 17 minutes.
