speed is the change in distance per time
in the question , they gave us the parameters for Speed and time , and they are asking us to get distance
the formula for Speed is S=d/t
making distance the subject of formula
the formula become
d=SรT
D=335ร5
=1675m

you don't need to stress yourself with newton's laws of motion ok.
this is just a straightforward question

this is the best app so far
last year i used this app to practice and i got 227 in the utme exams
i recomend it for all jamb students

We will use this first formula to find the acceleration:V=u+at,the answer is 67m/s^2
Then we find the distance with the second formula:S=ut+1/2 at

Since the aircraft is flying horizontal in the sky it is moving with a horizontal component of the velocity look
V = u + gt
but since it is a horizontal movement the gravity does not change and g is assigned 0
Vx = Ux
S = UxT
(Vx)^2= (Ux)^2
