Answer: the price of one nation's currency in terms of the currency of another nation.
Explanation: The rate of exchange can simply be explained as the worth or value of a country's currency in terms of the currency of another country. It gives an aggregate amount of the value of currency held by a certain person or spent in a particular country in terms of the currency of choice in another country. The exchange rate of currencies is usually determined by the market forces of demand and supply even though some aren't. For example, the rate at which one can convert a certain amount of British pounds to it's equivalent amount in U.S dollar is the exchange rate of British pounds to U.S dollars.
