Some red and some black pens area sold in packages of 20. The red pens are worth 50 cents each and the black pens are worth 30 cents each. The package of twenty pens is worth $8.20. How many black pens are in the package?

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
