Amodel airplane flies 18 feet in 2 seconds. what is the airplanes speed and miles per hour? round your answer to the nearest hundredth

Find out how many feet per second- 18 feet/2 sec = 9 feet per second Convert seconds to hours and get feet per hour. 60 seconds per minute * 60 minutes/hour = 3600 seconds/hour so the plane moves 9 feet/second * 3600 seconds/hour or 32400 feet/hour Convert feet to miles for the answer (32400 feet/hour) / 5280 feet/mile = 6.136 miles/hour
