This begs the question ... what units of bit rate do you want?

I have to choose one of these: -0,46Mbps -0,25Mbps -510 kbps -0.9 Mbps -250Kbps Last edited by skipjack; June 12th, 2016 at 02:12 PM.

Since the question asks for 3 significant figures I think the fifth choice, 250 Kbps is correct. Thanks from manus

Hmm, is this because the problem stated 15 Mb/min and not 15.0 Mb/min? If not, please take a moment and explain your reasoning to me.
