Exchange Rate Determination Topic

Hi, I have been finding difficulty in this question .Can someone help? please
The spot bid-offer rates between Australian dollar and pounds (GBP/AUD) is
quoted as 0.5144 – 0.5149. Speculator A expects the exchange rate to be 0.5130
– 0.5140, whereas Speculator B expects the exchange rate to be 0.5150 –
0.5155, in two months from the initial quotes.
a) Based on the expectations of the two speculators, which currency will
appreciate and which currency will depreciate from the view of
Speculator A, and Speculator B?
b) Determine the appropriate strategy between buy-low-sell-high, and
short-sell positions on the AUD that each Speculator (A and B) should
take given the bid-offer rates at t = 0 and their respective expected rates
t = 2 months, to realize a profit.
c) Based on your answers to part (b), calculate the profit in basis points for
the different positions taken by Speculator A and B, respectively.
