My teacher posted a practice exam with no answers so I want to make sure I am doing my problems right.(adsbygoogle = window.adsbygoogle || []).push({});

A car battery is rated at 70 A-hrs. How many minutes can this battery last if it operates at a current of 15A?

I made an equation 70A/60min = Xmin/15A

So, X=17.5 min

Am I right?
