The distance it travels in miles, d, is related to the time in seconds, t, by the equation
. (1)
To find : The distance traveled by airplane travel in 30 seconds to New York to Los Angeles.
We substitute the value of t= 30 in equation (1) , we get

i.e. the distance traveled by airplane travel in 30 seconds to New York to Los Angeles = 4.5 miles.
