kriegera said:Still a little lost here:
In general, at 68 F (20 C) sound travels at 1130 ft/sec (344.4 m/sec.)
3 miles = 15 840 feet
3 miles = 4 828.032 meters
but not sure how to put it together in equation format?
DaveC426913 said:Really?
You've got a velocity and a distance; you're being asked to solve for time.
You say you're tried over and over. Show your attempts.

T=15840 ft/ 1130ft/s = 14.018 seconds.

Air temperature can affect the time on a watch in two ways. First, extreme temperatures can cause the battery to drain faster, resulting in a loss of time accuracy. Second, extreme temperatures can cause the internal mechanics of the watch to expand or contract, which can also affect its accuracy.
Yes, a change in air temperature can have an instant effect on the time displayed on a watch. This is especially true for digital watches that rely on battery power, as extreme temperatures can drain the battery quickly. For mechanical watches, the effects may be more gradual, but still noticeable.
The ideal temperature range for maintaining accurate time on a watch is between 41°F (5°C) and 95°F (35°C). Outside of this range, the watch may experience inaccuracies due to the effects of extreme temperatures on its internal components.
To keep your watch accurate in extreme temperatures, it is important to avoid exposing it to temperature extremes. This can be done by removing the watch when entering environments with extreme temperatures, such as a sauna or freezer. Additionally, keeping the watch in a cool, dry place when not wearing it can also help maintain its accuracy.
Certain types of watches, such as dive watches, are designed to withstand extreme temperatures and pressure changes. These watches are typically sealed and have more robust internal mechanics, making them more resistant to the effects of temperature changes. However, it is still important to avoid exposing any watch to extreme temperatures to ensure accurate timekeeping.
