(40 miles per hour) / (3,600 seconds per hour) = 0.0111 mile per second (rounded, repeating)
What I do know is it takes 5 seconds for the sound waves to travel 1 mile.So, if it's 5 seconds per mile, take 40 seconds and divide by 5 and the answer is 8 miles. That means if you count 40 seconds and hear the thunder, the flash was 8 miles away.One more thing, every second, the sound travels .2 miles.
800 feet in 2 minutes 40 seconds equates to 3.41 miles per hour.
40 kph = 24.8 mph
A 100 m.p.h. fastball tavels at almost 147 feet per second, taking approximately .4 seconds to reach the catcher's glove after the pitcher releases the ball from the pitcher's mound. Therefore, a baseball (or any other object) will travel approximately 1.47 feet per second for each mile per hour of velocity. In order to calculate how long the pitch takes to reach the catcher after being delivered by the pitcher, divide 40 by the speed in miles per hour of the baseball to get the time in seconds.
You have to run at the speed of a mile per 3 2/3 minutes.
About 9 minutes 40 seconds.
3.15 minutes which is extremely fast
(40 yards) / (4.5 seconds) times (3,600 seconds per hour) / (1,760 yards per mile) =18 and 2/11 miles per hour
40 mph = 40 miles in one hour or 0.6666666r miles per minute. 40 miles an hour = 2/3 mile a minute An hour per 40 miles = 1.5 minutes a mile = 90 seconds a mile
(40 miles per hour) / (3,600 seconds per hour) = 0.0111 mile per second (rounded, repeating)
30 more seconds
40 minutes and 32 seconds He meant in miles per hour
21.75 miles per hour
1 minute 30 seconds at 40 mph
You will be moving at a pace of 90 miles per hour.
It is going about 9.3 yards per second; 40/4.3.
