the distance at both people will meet is 4.6 km
step by step explanation
the point at which both people meet is found by using the formula
Tan (θ) = perpendicular/base
Tan (30°) = x/8=4.6 km
this is because the person traveled 8 km to south and then making and angle of 30° turned north
distance traveled by the person b is found out as
Cos (θ) = base/ hypotenuse
Cos (60°) = 4.6/y=9.2 km
13.8 km is the total distance traveled by person b but he traveled 4.6 km before he turned north
