I think it should be 110ms .. 100K/1MBPS = 100ms for transferring the program and 8 ms of latency.
The RR quantum should be sufficient to accommodate the two.
so 110ms should suffice.
But frankly I think something is missing in the question. They should have given the rate of program processing, i.e. when the program is in the main memory, then at what rate it can be processed..
