Amodel airplane flew a distance of 330 ft in 15 seconds. select all the unit rates that are equivalent to the speed i don't know what to do 15 miles per hour 1,320 ft per minute 12 miles per hour 1,056ft per minute how do i do the work

Okay. So we will solve this by seeing how many feet is in one second. The model airplane flies 22 feet in one second. I can tell you that the model airplane does fly 1,320 ft per minute, because 22 * 60 equals 1,320, not 1,056 ft per minute. It travels 15 miles an hour, because there are 5,280 ft in one mile. When you multiply 1,320 by 60, you get 79,200 ft. Divide that number by 5,280 and you get 15 miles, not 12 miles per hour. All of the unit rates equivalent to the speed are 15 miles an hour and 1,320 ft per minute.
