An airplane is flying from New York city to Los Angeles.The distance it travels in Miles, D, is related to the time in seconds,

deff fn [24]

We have been given an equation $d=0.15t$ that represents the distance an airplane travels in Miles (d) is related to the time in seconds (t).

A. Upon substituting t=1 in our equation we will get,

$d=0.15\times 1$

$d=0.15$

We can see that our plane is travelling at rate of 0.15 miles per second.

$\text{Speed of plane }=0.15\frac{\text{miles}}{\text{second}}$

Therefore, plane is flying at the rate of 0.15 miles per second.

B. To find distance traveled by airplane in 30 seconds we will substitute t=30 in our given equation.

$d=0.15\times 30$

$d=4.5$

Therefore, plane will travel 4.5 miles in 30 seconds.

C. To find time it will take to travel 12.75 miles we will substitute d=12.75 in our given equation.

$d=0.15\times t$

$12.75=0.15\times t$

$t=\frac{12.75}{0.15}=85$

Therefore, plane will take 85 seconds to travel 12.75 miles.

Mercury is about 57,000,000 from the sun,whereas neptune is about 4.5 x 10 to the 9th power km from the sun. What is the differe

slavikrds [6]

Answer:

4,443,000,000 or 4.443 * 10^9 km.

Step-by-step explanation:

Neptune's distance from the sun = 4.5 * 10^9

= 4,500,000,000 km.

The required difference is

4,500,000,000 - 57,000,000

= 4,443,000,000 or 4.443 * 10^9.
