Does years old have a hyphen?

Because hour is typically pronounced with a silent h, an hour is correct. I wrote a blog post about an vs a on the EL&U blog some time ago, and it covers a wide variety of other cases that you might be interested in. An hour is correct, because “hour” begins with a vowel sound.

What does 100 percent faster mean?

100% faster means speed is increased by 100%, i.e., double speed. So, you don’t reduce time by 100%, but by 50%. If it’s 200% faster, you get 3x speed. In your example, you’d charge the battery in 2.5 and 1.6 minutes, respectively.

Do we say an hour or a hour?

You should say, ‘an hour’ (because hour begins with a vowel sound) and ‘a history’ (because history begins with a consonant sound). You should say ‘a union’ even if union begins with a ‘u’. This is because the pronunciation begins with ‘yu’, a consonant sound.

What does 200 percent increase mean?

An increase of 100% in a quantity means that the final amount is 200% of the initial amount (100% of initial + 100% of increase = 200% of initial). In other words, the quantity has doubled. An increase of 800% means the final amount is 9 times the original (100% + 800% = 900% = 9 times as large).
