Answer 2

The way it's written out is a bit confusing to understand so I'll re-write what the correct way should look like and you can check if you got the same answer

Answer 3

\[\frac{9 km }{ h }\times \frac{ 1hr }{ 60\min }\times \frac{ 1\min }{ 60\sec }\times \frac{ 1000m }{ 1km }=?\]

Answer 4

So that the units cancel out and you're left with m/s

Answer 6

Are your units written in fraction form?
