Question

The Ramirez family trip took six hours and I drove 330 miles the miles varies directly with the time they traveled

write a direct variation equation to represent this situation
how far could they travel in 12 hours?

Answer 1

In this case you have to multiply to solve. So, you multiply the # of miles TIMES the number of hours. We know that the unit rate is 330 mph. So we multiply that with 12 hours. 12*330=3960.

By checking you must divide 3960 by 12. 3960/12=330
