To find the number of pints per hour that the hose will fill the tub, we need to convert the rate of filling from ounces per minute to pints per hour.
Rate of filling = 4 ounces per minute
First, we need to convert the rate of filling from ounces to pints. Since 16 ounces = 1 pint, we can divide the rate of filling by 16 to get the rate in pints per minute.
Rate of filling in pints per minute = 4 ounces per minute / 16 ounces per pint = 0.25 pints per minute
Next, we need to convert the rate of filling from minutes to hours. Since 60 minutes = 1 hour, we can multiply the rate of filling in pints per minute by 60 to get the rate in pints per hour.
Rate of filling in pints per hour = 0.25 pints per minute * 60 minutes per hour = 15 pints per hour
Therefore, the hose will fill the tub at a rate of 15 pints per hour.

To find the number of pages the printer can print in 1 hour, we need to multiply the rate of printing (in pages per minute) by the total number of minutes in 1 hour.
Rate of printing = 8 pages per minute
Total minutes in 1 hour = 60 minutes
Number of pages printed in 1 hour = 8 pages per minute * 60 minutes = 480 pages per hour
Therefore, the printer can print 480 pages in 1 hour.

To find the speed of the pickleball in feet per minute, we need to convert the speed from miles per hour to feet per minute.
Speed of the pickleball = 100 miles per hour
First, we need to convert the speed from miles to feet. Since 5,280 feet = 1 mile, we can multiply the speed by 5,280 to get the speed in feet per hour.
Speed in feet per hour = 100 miles per hour * 5,280 feet per mile = 528,000 feet per hour
Next, we need to convert the speed from hours to minutes. Since 60 minutes = 1 hour, we can divide the speed in feet per hour by 60 to get the speed in feet per minute.
Speed in feet per minute = 528,000 feet per hour / 60 minutes per hour = 8,800 feet per minute
Therefore, the speed of the pickleball is 8,800 feet per minute.

To find the speed limit in miles per hour, we need to convert the speed from kilometers per hour to miles per hour.
Speed limit in Europe = 80 km per hour
Since there are about 1.6 kilometers in 1 mile, we can divide the speed limit in kilometers per hour by 1.6 to get the speed limit in miles per hour.
Speed limit in miles per hour = 80 km per hour / 1.6 kilometers per mile = 50 miles per hour
Therefore, the speed limit in Europe is 50 miles per hour.
