Dimensional analysis is basically a sciance in which a
relationship is defined between two physical quantity
that is one quantity is represented in the from another
quantity.
Now,
$$\displaystyle{0},{82}{G}{B}{P}={1}{U}.{S}.{d}{o}{l}{l}{a}{r}$$
$$\displaystyle{1}{G}{B}{P}={\frac{{{1}}}{{{0.82}}}}{U}.{S}.{d}{o}{l}{l}{a}{r}$$
$$\displaystyle{3000}{G}{B}{P}={\frac{{{1}}}{{{0.82}}}}\times{3000}{U}.{S}.{d}{o}{l}{l}{a}{r}$$
$$\displaystyle{3000}{G}{B}{P}={3658.537}{U}.{S}{d}{o}{l}{l}{a}{r}$$
t So,the trip costs 3 thousand GBP will be equal to 3659U.S. dollar
