I'll give you a question, please answer with step-by-step reasoning process.
Darma can eat 20 peanuts in 15 seconds. At this same rate, how many peanuts could she eat in 6 minutes?

480
There are 60 * 6 = 360 seconds in 6 minutes.

Then there are 360 / 15 = 24 sets of 15 seconds.

So, Darma could eat 24 x 20 = 480 peanuts.

.

The final answer: 480
