Answer:2688.63 miles
Step-by-step explanation:
Given
Distance between Paris and Los-Angeles
wind blows from Los Angeles to Paris with 100 mph
Velocity of Plane in still Air is
Relative velocity of A is because Plane A is flying opposite to wind
Relative velocity of B is
Plane A leaves At 12 noon
distance traveled by Plane A in 1 hr
Net distance between two Planes is
Suppose they meet after t hr
Distance traveled by Plane B in t time
distance traveled by Plane A in t hr is
Total distance is 4550 miles
Distance traveled by B is
i.e. they meet at a distance of 2688.63 miles from Los Angeles
