Question

If a farmer takes 2 hours and 10 minutes to plough a field, find the time taken by the farmer to plough two fields.

• A. 3 hours and 20 minutes
• B. 4 hours and 10 minutes
• C. 4 hours and 20 minutes
• D. 5 hours and 10 minutes

Answer 1

The correct option is C 4 hours and 20 minutes

Time required to plough one field = 2 hours and 10 minutes

Time required to plough two fields = 2 $\times$ Time required to plough one field

Time required to plough two fields = 2 $\times$ (2 hours and 10 minutes)

Time required to plough two fields = 4 hours and 20 minutes
