When a thunder and lightning storm approaches, you can calculate approximately how far away the storm is (in miles) by counting the time, in seconds between seeing the lightning and then hearing the thunder.
The table below shows the relationship between the seconds counted and how far away the storm is.

If the time is represented by the letter t and the distance by the letter d, write the general rule that will help find the distance if the time is known.
According to various sources and studies, you can estimate the outside temperature by counting the chirps of a snowy tree cricket!
One study found that when the temperature is 70 degrees Fahrenheit, the cricket chirps 30 times in each time period of 14 seconds. When the temperature is 80 degrees, the cricket chirps 40 times in the same time period. And when the temperature is 85 degrees it chirps 45 times.
