By way of some "round" math, (rounding quotients to the nearest whole numbers), I have
extrapolated 5 seconds as a decent "Rule of thumb".
Thunder will go *approximately* 1 mile every 5 seconds, at average.
Humidity, elevation, etc. affect air density, which affects the speed of sound, but negligibly for this answer.
So, see the flash, count 5, 1 mile (approximately).
A quick rule of thumb is 5 seconds. Since sound travels at a little over 1000 feet per second which is about a fifth of a mile. A better estimate is 1125 feet per second. 5280 / 1125 = 4.693 seconds
It take the light to travel for 2 million years Actually about 100 years, maybe less.
Lightning is seen earlier because light travels faster than sound. Lightning occurs first and produces light, which reaches our eyes immediately. Thunder, on the other hand, is the sound produced by the rapid heating and cooling of air around the lightning bolt, which takes longer to travel to our ears.
Depends witch star it comes from. The closest stars light will only take 7 years but most of the stars (that are relatively closeby compared to the light of other galaxies) will take 200 or more.
The time it takes for a radiator to freeze at 30°F would depend on various factors, such as the initial temperature of the radiator, its size, the surrounding temperature, and the material it is made of. In general, it could take several hours to freeze completely at that temperature. Cooling rates can vary significantly based on these factors.

18 seconds to travel a mile at 200 mph.
55.4 seconds per mile at 65mph
It depends on the speed at which you travel.
20 seconds.
That depends on its speed.
It depends on it's speed.
it would take 1 hour to travel a mile going at 60 mph
2 mintes
About 40 seconds.
