ANPR system takes two images of each passing car. each image is 840 pixels wide and 320 pixels high. each pixel is stored in one byte. on average six car pass per minute. if each uncompressed image is sent back to the control centre for processing, what is the average rate of data transfer?

i got six options 2400bps,927.2kbps,7.6Mbps,1642 bps,650.4kbps,430kbps.

so 12 images per minute, or 1 image per 5 seconds. I don't see an answer.
