How Does the Block Time of a PoW Chain Affect Its Transaction Speed?

The block time is the average time it takes for the network to generate a new block. A longer block time, such as Bitcoin's 10 minutes, means that transactions must wait longer to be included in a block and receive their initial confirmation, directly limiting the overall transaction speed and throughput of the network.
