28.65 seconds for 50 yards would be the same as 31.33 seconds for 50 meters.
Meters.
You need to multiply the speed of the wave by the time. You may also need to convert the units, to make them compatible. For instance, if the speed of the wave is expressed in meters per second, you would need to convert the minutes to seconds.
True
Meters or feet. It is usually meters though. Eg: 2.1M
It would convert to 10.5 seconds for 100 meters.
A 220 yard dash time of 21.80 seconds translates to a time of 21.67 seconds for 200 meters.
It wouldn't be. If you're swimming in meters the pool should be 50 meters, and I've seen them be 25 meters occasionally. If you're swimming in yards the pool would be 25 yards.
11.99 seconds because 100 yard dash is 91 meters. 100 meters/91 meters = 1.09 Then do 11 seconds x 1.09 = 11.99 seconds. If you round it, you basically be getting a 12 second 100 meter dash.
You can't convert meters to square meters.
400 meters/80 seconds = 5 meters/second.
In order to convert meters to kilometers you would go meters divided by 1000 = kilometers. So your answer is 0.0057104.
it would take 75 seconds
This question doesn't make a lot of sense. Maybe something is missing? To convert seconds to metres per second you would need to divide the metres given by the number of seconds used. If all you have is seconds, and no distance, then you are stuck. Metres per second is a measure of speed and seconds is a measure of time. Speed=distance/time. So divide your metres by your seconds to get metres per second.
You cannot convert 400 meters to 3 kilometers. They are two different lengths. 1 kilometer = 1,000 meters. 3 kilometers would be 3,000 meters. 400 meters would be 0.4 kilometers
2 seconds
Divide by 1,000.
