Question

A Nigerian importer requires British Pounds ($\text{GBP}$) to settle an international trade transaction. In the foreign exchange market, the exchange rate between the US Dollar ($\text{USD}$) and the Nigerian Naira ($\text{NGN}$) is $\$1.00 = \text{NGN } 750$, while the exchange rate between the British Pound ($\text{GBP}$) and the US Dollar ($\text{USD}$) is $£1.00 = \$1.40$. What is the cross exchange rate of one British Pound ($£1.00$) in terms of Nigerian Naira ($\text{NGN}$)?
