Risk management

Dear sir,
I have a doubt with this question

A UK company expects to receive $500,000 in 5 months’ time.
Current Exchange rate 1.7456$/£ + 0.0002
3 month exchange rate 1.7725$/£ + 0.0005
9 month exchange rate 1.8035$/£ + 0.0005
Calculate receipts in £ if forward hedge is taken (to the nearest ‘’000’’ round off)?

My question is if its due in 5 months shouldn’t we get an exchange rate for 5 months? How do we solve the problem?

Thanks!
