Explaintion

Money, time, and measurements can be plural or singular. If the focus of your sentence is a total amount, use a singular verb. If the focus of your sentence is on multiple units, use a plural verb.

Sometimes it's difficult to tell whether to use a singular or plural verb, but there's an easy way to figure it out—just think about your sentence as the answer to a question. If to get your answer you can ask questions like how much? how big? how small? or how long?, use a singular verb. These questions suggest a total amount.
