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.
What is width?
The width of something is the measurement of one side of a body. It is generally less than length of that body or shape.
How to calculate time?
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.
Answer:
70 mins
Step-by-step explanation:
This is called inverse proportion.
1hr : 14in
x hr : 12in
Ask yourself, what do you do to 14 to get 12? To find this out, we do:
14 / 12 = 1.16666667
Since the blade is smaller, it will take longer. So, we times 1hr by 1.16666667 to get
1.16666667 hrs =
1.17 hours (rounded)
This is 70.2 mins, or 1hr 10 mins
Hope this helps!
