SOLUTION: your distance from a lightening strike can be estimated using the time between observing the lightening flash and hearing its thunder. a delay of one sec implies a distance of 0.2

Question 1112866: your distance from a lightening strike can be estimated using the time between observing the lightening flash and hearing its thunder. a delay of one sec implies a distance of 0.2 mi, 2 sec implies 0.4 mi, and so on. write a simplified explicit formula for this arithmetic sequence and find the distance implied by a 9 sec delay.

-------
d = t/5 --- d in miles, t in seconds.
----
d = 9/5 = 1.8 miles
====================
PS lightning, not lightening
----
I prefer using d = 1100t --- d in feet, t in seconds
