Answer:
$70
Step-by-step explanation:
break it down, 100% of 40 is 40, and 75% of 40 is 30, so add 40 and 30 to get 70
We have been given an equation
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,

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

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.



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