The velocity of a boat relative to water is represented by \(\displaystyle 3\hat{?} + 4\hat{?}\) and that of water relative to earth is \(\displaystyle \hat{?}− 3\hat{?}\) . What is the velocity of the boat relative to earth if \(\displaystyle \hat{ ?}\) and \(\displaystyle \hat{?}\) represent one KM an hour east and north respectively?
