Kiya drives her car 20 km west from her home, then turns left and goes 20 km more, then, she turns right and goes 10 km and then she turns right and goes 15 km, finally she goes 30 km more after turning right again. At what distance is she from the starting point?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 05 km
Each turn is taken from the direction she is facing at that moment:
She starts driving West (20 km)
Facing West, a left turn is South (20 km)
Facing South, a right turn is West (10 km)
Facing West, a right turn is North (15 km)
Facing North, a right turn is East (30 km)
West–East: \(20+10=30\) km West, then 30 km East, so she is back in line with her home
North–South: 20 km South, then 15 km North, so she is \(20-15=5\) km South of her home
