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

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

Answer:

Speed, v = 2.743 m/s

Step-by-step explanation:

Given that,

Distance covered by the airplane, d = 18 ft

Time taken by the airplane, t = 2 s

Speed of the airplane is calculated by finding the total distance and dividing it by total time taken. Mathematically, it is given by :

\(v=\dfrac{d}{t}\)

\(v=\dfrac{18\ ft}{2\ s}\)

v = 9 ft/s

Since, 1 foot/second = 0.3048 m/s

So, the speed of the model airplane is 2.743 m/s. Hence, this is the required solution.
