The distance traveled by the arrow and horizontal velocity are directly proportional, thus when the distance increases, an increase in initial velocity will allow the arrow to hit the target.
<h3>
Time of motion of the projectile</h3>
If the horizontal distance the projectile would travel before hitting the target is 70.67 m, the time of motion of the projectile is calculated as;
X = Vx(t)
t = X/Vx
t = X/Vcosθ
t = (70.67) / (45 x cos10)
t = 1.6 s
When the archery target is moved further away from the archer, the archer needs increase the initial velocity of the arrow assuming the angle of projection is constant.
Since the distance and horizontal velocity are directly proportional to each other, thus when the distance increases, an increase in initial velocity will allow the arrow to hit the target.

Answer:
the length of resultant vector is 5 inches
Explanation:
In the attachment, you will see X vector along the X axis and Y vector along the Y direction. Let the resultant vector be denoted by
The resultant vector always start from the tail of first vector and ends at the head of second vector.
Since it is a right angled triangle, so the result of resultant vector is found by using Pythagoras theorem i.e.
So, when we plug in the values of X = 48 and Y = 14
Therefore, the length of resultant vector is 5 inches.
