Question: 1 / 525

What is the data rate of a DVD played at 2x speed?

1.35 MB/sec

2.7 MB/sec

A DVD played at 2x speed has a data rate of 2.7 MB/sec. This means that the DVD player is reading and transmitting data at a speed that is twice as fast as the original data rate of the DVD, which is 1.35 MB/sec. The other options listed (1.35 MB/sec, 5.4 MB/sec, and 10.8 MB/sec) are incorrect because they are not double the original data rate. 1.35 MB/sec is the original data rate, 5.4 MB/sec is 4 times the original data rate, and 10.8 MB/sec is 8 times the original data rate. Therefore, the correct answer is B as it is the only option that reflects a data rate that is twice as fast as the original.
