To find an average, add all the speeds of each arrow together and divide that number by the total number of arrows shot.
example:
Arrow 1:
20mph
Arrow 2:
23 mph
Arrow 3:
23 mph
= 20+23+23 = 66
66÷ 3= 22 mph on average
The answers are A and B. hope this helps, have an amazing day :)

<h3>What is Reflection Symmetry ?</h3>
A symmetry in which one half of the object is symmetrical to thew other half
A square has 4 lines of reflection symmetry , 2 along its sides and 2 along its diagonals
A regular hexagon has 6 reflection symmetry , three along the midpoints of the sides and three along the daigonals
A Trapezium can have 0 or 1 lines of symmetry depending upon the length of the non parallel sides.
An equilateral Triangle has 3 lines of reflection symmetry , an isosceles has 2 lines of symmetry and a scalene triangle has no lines of symmetry.
