 Homework Statement:

An aircraft is flying at a height of 3400 m above the ground. If the angle subtended at a ground observation point by the aircraft positions 10.0 s apart is
30 degrees. What is the speed of the aircraft?
 Relevant Equations:
 s=vt, where s is the distance travelled at a speed of v in time t
When I attempted this problem, I came up with two different solutions and answers, and both seem correct to me. However, the answer obtained by the first method is correct according to the book.
The methods I used are as in screenshots below.
Isn't the problem statement ambiguous, or maybe I am missing something?
In diagrams below, point ##G## is the observation point on the ground, ##P_1## is the initial observed position of the aircraft and ##P_2## is the final observed position of the aircraft.
