Step 1: Calculate the duration of the lecture at 2.5x speed

The original lecture is 2 hours long. If you watch it at 2.5x speed, the duration will be 2 hours / 2.5 = 0.8 hours.

Step 2: Convert the duration to seconds

There are 3600 seconds in an hour. So, the duration of the lecture at 2.5x speed in seconds is 0.8 hours * 3600 seconds/hour = 2880 seconds.

Step 3: Calculate the size of the lecture in bits

The size of the lecture is given as 400MB. There are 8 bits in a byte and 1024 bytes in a kilobyte and 1024 kilobytes in a megabyte. So, the size of the lecture in bits is 400MB * 1024 * 1024 * 8 = 3355443200 bits.

Step 4: Calculate the minimum theoretical bit rate

The bit rate is the number of bits that are conveyed or processed per unit of time. In this case, it's the number of bits of the lecture (3355443200 bits) divided by the duration of the lecture at 2.5x speed (2880 seconds). So, the minimum theoretical bit rate is 3355443200 bits / 2880 seconds = 1165088.89 bits per second, or approximately 1.165 Mbps.

So, to seamlessly stream the lecture without buffering, your internet connection should have a minimum theoretical bit rate of approximately 1.165 Mbps.
