Choose the correct article: The car was travelling at 120 kilometres ___ hour.
Explanation
When expressing a rate ('per/each'), we use 'a/an'. 'Hour' has a silent 'h' (vowel sound), so 'an hour'.
Reference: English Grammar: Articles (Complete Notes) , Page 5
Hint
Rates use a/an; mind the silent 'h'.
