Problem Solving Steps:
1. Draw a rough diagram of the given problem.
2. Analyze the given data and draw conclusions.
3. Calculate the distance and direction from the starting point.
1. Diagram:
Starting point → 30 km North → 15 km East → 30 km Right
2. Analysis:
Ritu goes 30 km towards North from a fixed point = 30 km North
After turning right, she goes 15 km = 15 km East
After turning right again, she goes 30 km = 30 km South
So, Ritu is now 15 km East and 30 km South from the starting point.
3. Calculation:
Using Pythagoras theorem, we can calculate the distance from the starting point.
Distance = √(15² + 30²) = √(225 + 900) = √1125 = 15√5 km
The direction can be found using trigonometry.
Tanθ = Opposite/Adjacent = 30/15 = 2
θ = Tan⁻¹2 = 63.4 degrees
Therefore, Ritu is 15√5 km away from her starting point in the East direction at an angle of 63.4 degrees.
Hence, the correct answer is option 'B': 15 km, East.
