Answer: 8 minutes
Step-by-step explanation:
You need to find the rate at which he peels the oranges (you need to first find out how many minutes he takes to peel per minute). To do this you need to:
- divide 20 minutes by 4 to find how many minutes he takes to peel each orange
- you will get 4 minutes per orange
- then you can multiply 4 minutes times 2 oranges which gives you 8 minutes
Therefore, it takes him 8 minutes to peel 2 oranges (assuming that he peels the oranges at a constant speed)
