<human>:  Matt buys a massager. At the lowest setting, it vibrates at 1600 vibrations per second. At the highest setting, it vibrates 60% faster. Matt uses it for 5 minutes at the highest setting. How many vibrations does he experience?
<bot>: How fast does it vibrate at the highest setting? ** At the highest setting, it vibrates 1600*.6=<<1600*.6=960>>960 vibrations per second faster than the lowest setting
How fast does it vibrate at the highest setting? ** So it vibrates at 1600+960=<<1600+960=2560>>2560 vibrations per second
How many seconds does Matt use the massager? ** Matt uses it for 5 minutes so that is 5*60=<<5*60=300>>300 seconds
How many vibrations does Matt experience? ** That means he experienced 2560*300=<<2560*300=768000>>768,000 vibrations
