let P be the position of the observer and point A the position of the plane directly above him

let B be the position of the plane 1 minute later

let the height AP be h miles

mark the angle of elevation as 34°, then angle PBA = 34°

in 1 minute the plane has traveled (1/60)540 or 9 miles

so AB = 9

h/9 = tan34°

h = 9tan34° = 6.07 miles

height of plane = 6.07 miles

distance covered in 1 minute = 9 miles
