In Holland ( where i was born and grew up) I learned that there are 5 continents; America, Europe, Asia, Africa and Australia. But when I moved to Canada I found out that you learn that there are 7; Asia, Europe, Antarctica, Australia, North America, South America and Africa. So what how many are there really? Or it doesn't really matter just stick to whatever the country you are in believes in?:P

...because it always puts the child at risk.

(Can you name me something, anything, that doesn't put a child or adult at risk?? Doesn't giving a child a penny put them at risk because it can be swallowed? Isn't every person walking down the street "at risk"?

The problem goes as follows--- " A car can travel 11 km for every liter(L) of gas it uses (26 mi/gal). If the driver's average speed is 28 km/h (18 mi/h), how many hours can the driver travel before emptying a full 35 L gas tank." I have to show work, so please don't just answer the question. If possible, please explain what I need to do.
