To find the distance from the starting point, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, the east and north directions form the two sides of a right triangle, and the distance from the starting point is the hypotenuse.
Using the Pythagorean theorem, we can calculate:
Distance^2 = (3^2) + (6^2)
Distance^2 = 9 + 36
Distance^2 = 45
Taking the square root of both sides, we get:
Distance = √45
Rounding to the nearest whole number, the distance is approximately 6.7 m.
Therefore, the correct answer is 6.7 m.
