When you send a transaction, what is a likely time frame for it to be mined on the Ethereum network?

1-5 seconds
5-10 seconds
10-30 seconds
30-60 seconds

The correct answer is: 10-30 seconds

When sending a transaction on the Ethereum network, the time frame for it to be mined typically falls within 10 to 30 seconds. This duration can vary based on factors such as network congestion, gas fees, and the current block time of the Ethereum network, which averages around 12 to 15 seconds per block. Transactions with higher gas fees are prioritized and may be confirmed quicker, while those with lower fees may take longer, especially during peak times. However, under normal operating conditions, expecting a transaction to be mined within the 10 to 30 seconds range aligns well with the average block generation time and typical transaction confirmation speed.
