Answer:
Step-by-step explanation:
velocity of river with respect to ground = 4 mi/h south
Velocity of swimmer with respect to river = 2 mi/h east
According to the formula of relative velocity
Where, V(S,G) be the velocity of swimmer with respect to ground, it is true velocity of swimmer.
-x + 1/2 = x + 4 1/2
+x +x
1/2 = 2x + 4 1/2
-4 1/2 - 4 1/2
-4 = 2x
x = -2
