Discussion Overview

The discussion revolves around calculating the time required to mow 295 hectares using a mower with specific dimensions and speed. The focus is on the mathematical approach to the problem, including the validity of certain mathematical operations.

Discussion Character

  • Mathematical reasoning

Main Points Raised

  • One participant seeks to determine the number of days needed to mow 295 hectares with a mower that has a 12-foot wide blade and operates at 4 km/h.
  • Another participant asserts that cross multiplication can be applied to numbers, regardless of how those numbers were derived, including through squaring.
  • A subsequent post questions the correctness of the equation presented in a photo, indicating uncertainty about its validity.

Areas of Agreement / Disagreement

Participants express differing views on the correctness of the mathematical approach and the application of cross multiplication, indicating that the discussion remains unresolved.

Contextual Notes

There is uncertainty regarding the mathematical steps involved in the calculations and the assumptions made about the mowing process.

Hello!
I am new to math forums and am not even sure I’m in the right thread but will give it a go!
I am trying to determine how many days it will take to mow 295 hectares when my mower has a blade 12’ wide and can move at 4km/hour.
Attached is what I believe to be correct but am uncertain if you can cross multiply squared numbers.
Thanks in advance!

You can cross multiply NUMBERS. How you got the numbers, by squaring or other wise, is irrelevant.
 
Ok - does this look correct to you then?

Right, ok so then do you believe the equation in the photo to be correct then?
