Answer:
It takes 85 seconds to go 12.75 miles
Explanation:
We are given
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 T by the equation

we are given to find time when distance is 12.75 miles
so, we can set d=12.75
and then we can solve for T

We can divide both sides by 0.15


So,
It takes 85 seconds to go 12.75 miles
