In 9 hours 2 in of rain fell at this rate how many inches will fall in 12 hours

2 2/3 or

2.666667 inches rainfall or

8/3 inches of rainfall.

Step-by-step explanation:

Set up a proportion. Since you are going to be looking for inches of rainfall, it should go in the numerator.

2 in rainfall/9 hours = x / 12 inches.               Multiply both sides by 12

2*12 /9 = x

8/3 inches = x

2 2/3 inches should fall in 12 hours.

2.67 in

Step-by-step explanation:

∵ In 9 hours amount of rainfall = 2 in

∴ In 1 hours amount of rainfall = 2/9 in

∴ in 12 hours amount of rainfall = (2/9) × 12

                                                  =   =  

                                                 ≈   in or 2.67 in.

In 12 hours 2.67 in. rain fell.

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.
