Question 436983
The undefined plane for 1/12 hours travel {{{600*1/12=50}}}miles.

The remain distance between them when the jet take of is:122-50=72 miles.

Let assume that planes met x miles from the coast line.

The time that jet need to travel x miles is {{{x/264}}}

The time that the unidentified plane need to travel 72-x miles is:

{{{(72-x)/600}}}, since these are equal we write the equation:

{{{x/264=(72-x)/600}}}, solve this equation:

{{{x=22}}}miles.

Answer:The jet met the plane 22 miles from coast line.
