Answer:
The plane is flying at a speed of 0.15 miles/seconds
Explanation:
To determine how fast the airplane is flying, we will determine the speed of the airplane.
Speed can be calculated from the formula
Speed = Distance traveled / Time taken
From the question, the distance, d, the airplane travels in miles is related to time, t, in seconds by the equation d = 0.15t. This means after t seconds, the airplane has traveled 0.15t miles. Then we can write that
Distance traveled = 0.15t miles
and Time taken = t seconds
From the formula
Speed = Distance traveled / Time taken
∴ Speed = 0.15t miles / t seconds
Speed = 0.15 miles/seconds
Hence, the speed of the plane is 0.15 miles/seconds.
That is, the plane is flying at 0.15 miles/seconds.
