Average speed is the total distance traveled divided by the elapsed time. A car that travels 60 miles in one hour, stops for one hour and travels 60 miles for another hour, has an average speed of 120 miles / 3 hours, which is 40 mph.
If you are asking, "What is the meaning of the word 'variables' ", then a variable is an amount, one of the facts given, in a question. In the question, "How fast is a car going that travels 10 km in one hour?" The variables are: * 10 km in distance * 1 hour of time.
The approximate distance that light travels in one second.
In a rough, round figure? 930,000 to 1. Sound travels roughly 1/5 of a mile per second in air. Light travels 186,000 miles per second in a vacuum. In five seconds sound travels one mile. In five seconds, light travels 930,000 miles in a vacuum.
A light hour is the distance light travels in one hour in vacuum. One light hour equals 1.079*10^12 meters.
Light travels approximately 983,571,056 feet in vacuum in the time it takes sound to travel 1100 feet in air.
As distance increases, the intensity of sound decreases due to spreading out of the sound waves in all directions. This decrease in intensity leads to a reduction in loudness as the sound travels further from its source. At double the distance, the sound intensity will be one-fourth as strong.
Its speed relative to the speed of light. (Roughly sound travels at one mile per 5 seconds.)

32 miles per hour. The speed at which the car is travelling is the distance in miles that the car travels per hour. If the car travels 16 miles in 30 minutes it should then travel twice as far in one hour, since one hour is twice as long as 30 minutes (half an hour). So, the car travels 2 * 16 miles per hour, which equals 32 miles per hour.
Average speed is the total distance traveled divided by the elapsed time. A car that travels 60 miles in one hour, stops for one hour and travels 60 miles for another hour, has an average speed of 120 miles / 3 hours, which is 40 mph.
Light travels at approximately 3x108m/s whilst sound travels only at 343m/s. So which do you think is the faster one?
No, light year per hour is not a standard measure of speed. A light year is a measure of distance, not time. It represents the distance that light travels in one year.
In 8 seconds, sound would travel 8 times the distance it travels in 1 second. Therefore, in 8 seconds, sound would travel 8 x 344m = 2752 meters.
That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.
From central Brisbane to Surfers Paradise is a trip of around 74 km and takes just over an hour, depending on whether or not one travels in peak hour traffic.
