A Fast Duck Is Flying $( 20 \tilde { \mathbf { i } } + 40 \tilde { \mathbf { j } } )$

question 63

Short Answer

A fast duck is flying $( 20 \tilde { \mathbf { i } } + 40 \tilde { \mathbf { j } } )$ mi/h at the same altitude as a slow airplane flying with a velocity of $( - 80 \hat { \mathbf { i } } + 40 \tilde { \mathbf { j } } )$ mi/h.How fast and in what direction is the duck moving relative to the airplane?
