there are 5 more questions on this which are more complicated but want to get this (a) first. assume by speed they mean magnitude of the vector.

Toyundai speed is \(\displaystyle 30 \frac{km}{h} \)

Chryssalt speed is \(\displaystyle \approx 39 \frac{km}{h}\)

The arithmetic looks fine, but the question doesn't. Why do vehicles working north-south have east-west velocity components?
