calculate the chip rate of FSK

question: Input data at 75 bits/s are channel encoded using a rate 1/2 encoder. The coded bits are then modulated using 8-ary FSK. The FSK symbols symbols are then spread by frequency hopping at rate of 2000hops/s.

(i) What is the chip rate?
(ii) If there are two such signals, time division multiplexing(TMD'd) on the channel at the same time it is frequency hopped. How would this affect the chip rate and the symbol rate?

i need the answer please. thanks for helping.
