Could someone explain this question to me?
I attempted the question and here is why I chose the answer below.
Thank you!
--------------------------------------
1. If A ⃗ is a vector representing 50 km/h northeast, what is 3/5 A ⃗?
a) 30 km/h southwest
b) 30 km/h northeast
c) 30 km/h northwest
d) 30 km/h southeast
I attempted the question and here is why I chose the answer:
3/5(50)=30 km/h. It is northeast because the value is not negative. If it were to be negative, it would go south, so the answer is B

2. A ⃗ represents vector going 5km/h N20°E. What is -1/5 A ⃗
a) 5km/h S20°E
b) 1km/h S20°W
c) 1km/h W20°S
d) 5km/h S20°W
Answer is B, 1km/h S20°W because the value is negative, it is going south and west,thus opposite direction.
