I'm somewhat familar with the molecular basics of chemistry, but not so much the conversions. I'm stuck on this one:

5.850 gal/hr to L/s.

or...

2.998 x 10(to the 8th..don't know how to do exponents) m/s to km/hr?



So there's two conversions going on in each problem?

I have the answers in the back of my textbook, but I'm not sure how to get there. 

Any help at all would be appreciated :) Thanks!
