In a game, my friend is making 105 dollars per 45 seconds. how much money will he make in an hour?

Use the concept of the ratio

1 Hour = 60 Minutes = 3600 Seconds

105 Dollars : 45 Seconds

                ? : 3600 Seconds

So the type of the ratio is the direct ratio because when you work harder you get more wages.

So your friend will make $8,400 every hour he plays the game.

we don't have enough info to solve this
