Answer:
It will take 12 hours for 1 person to plough the field
Step-by-step explanation:
This question can be solved using proportion, but we need to first find-out whether it is a direct proportion or and indirect proportion.
As the number of people increases, the time taken to plough a field will decrease, as the number of people decreases, the time taken to plough the field increases. This is an indirect proportion, so the value will be arranged inversely to each-other.
Let x be the time taken for 1 person to plough the field.
2 people = 1 person
x = 6 hours
Cross-multiply
x × 1 = 2 × 6
x = 12 hours
It will take 12 hours for 1 person to plough the field
