Question

An airplane is flying from new york city to los angeles. The distace it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t. How fast is it flying?

Answer 1

Answer:

The plane is flying at a speed of 0.15 miles/seconds

Step-by-step 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.
