How to calculate Minimum transmission rate?

    Frames are generated at node A
    sent to node C through node B.
    What is the minimum transmission rate required between nodes B and C
    so that the buffers in node B will not flooded, based on the following
    figures:

    A<---4000--->B<-1000->C

    (i) the data rate between A and B is 100 Kbps.
    (ii) the propagation delay is 10 microsec/mile for both lines,
    (iii) there are full duplex lines between the nodes,
    (iv) all data frames are 1000 bits long; ACK
    frames are separate frames of negligible length,
    (v) between A and B, a sliding window protocol with a window size of 3
    is used, (vi)between B and C, stop and wait is used, (vii) there are no
    errors.

    Thanks in advances
