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

 June 8th, 2016, 11:59 PM #4 Newbie   Joined: Mar 2016 From: longon Posts: 7 Thanks: 0 Hi, this is the question: If it takes 1 minute to transmit 15 Mbits of data, what is the bit rate at which the data is being transmitted (to 3 significant figures)? 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.
