Answer:
convert the task into ratios
(1) if $24 = 4 walks
how many $ for a walk
= (24/4) $/walk
= $6 per walk
•the first one is correct
•the second is wrong, cause it interprete $12/3 walks, which is rationalized to $3 per walk
•the third one is correct, cause it can also be rationalized ($30/5walks) to $6 per walk.
also, rationalizing this would equate to 3 miles per hour (6miles/2hrs)
• one is wrong cause it's 4 miles per hour
•two is correct, it's saying 3 miles per hour (12/4)
• third, likewise is correct 3 miles per hour (9/3) miles/hrs
Find the 2 different rates at which the farm worker worked:
3 pints
--------- = 0.75 pint/min
4 min
2 pints
---------- = 0.67 pint/ min
3 min
Then you need to subtract 0.67 pint/min from 0.75 pint/min to answer this question.
Alternatively, subtract 2/3 pint/min from 3/4 pint/min.

Hey there James!
So, just remember, 2/5 is almost half of 1.
When it is almost half of 1, this means that it would have to be 2.5/5
This would mean that 4/10 would be your answer, because it is almost half of 1 also.
Hope this helps.
