Answer / Sumit Rajput

The frog takes 7 minutes and 6 seconds to reach the top of the pole. This is calculated by considering that for every minute, the frog makes a net progress of (3 feet - 2 feet) = 1 foot. So in 15 feet, he needs 15/1 = 15 minutes. Since the question mentions he slips down 2 feet after resting for a minute, we need to account for this by reducing the total distance climbed by 2 feet every minute. Therefore, there will be an extra slip during the 15th minute which consumes 2 more minutes (since he slips back 2 feet in 1 minute). So, the total time taken is 15 minutes + 2 minutes = 17 minutes.
