45%

Step-by-step explanation:

From the given histogram, The number of volunteers worked 8 to 11 hours = 5

The number of volunteers worked 16 to 19 hours = 4

The number of volunteers worked 8 to 11 hours or 16 to 19 hours =5+4=9

The percent of volunteers worked 8 to 11 hours or 16 to 19 hours is given by :-

Hence, the percent of the volunteers worked 8 to 11 hours or 16 to 19 hours =45%

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.
