Problema Solution
Find a formula for a function f that computes the distance (in miles) between an observer and a lightning bolt when the speed of sound is 1150 feet per second.
Answer provided by our tutors
let 't' represent the time in seconds between the appearance of the lightning bolt and hearing its sound
we ignore any delays introduced by the speed of light
feet per second * seconds = feet
1 mile = 5280 feet
f(t) expresses the distance in miles when 't' is expressed in seconds:
f(t) = (1150 * t) / 5280
