1 mile per hour = 22/15 = 1.4666... feet per second (rounded, repeating)The following are exact numbers:-- 15 miles per hour = 22 feet per second-- 30 miles per hour = 44 feet per second-- 60 miles per hour = 88 feet per second-- 90 miles per hour = 132 feet per second-- 120 miles per hour = 176 feet per second
3.5 (miles per second) = 20,277.73 km per hour.
4.7 metres per second is about 10.5 miles per hour.
It is a measure of acceleration. Every hour, the speed increases by 343 metres per second.
The speed of sound in air is approximately 343 meters per second. To convert this to miles per hour, multiply by 3600 seconds in an hour and then divide by 1609 meters in a mile. The speed of sound in air is roughly 767 miles per hour.
343/A hours
767miles/hour = 767 x 1609.344 meters/hour = 767 x 1609.344 meters / 3600 seconds = 343 meters per second (approx)
343/B hours
343/C hours
velocity = distance / time time = distance / velocity time = 343 miles / 70 miles per hour = 4.9 hours
The speed of sound through air at room temperature is about 343 meters per second (1235 kilometers per hour or 767 miles per hour).
1200 feet per second is equivalent to approximately 818 miles per hour.
70 miles per second is 252,000 miles per hour.
