Convert the meters to miles as follows using the "slash and burn" technique. Make sure your units cancel and you're left with the correct units at the end.
I alway remember that one inch equals 2.54 cm and there are 100 cm in a meter so.....
400 meters = 40,000 cm * 1 inch / 2.54 cm * 1 foot / 12 inches * 1 miles / 5,280 feet
= .24855 miles
Now, convert 1 minute and 42 seconds into hours
1 min 42 sec = 1 and 42/60 minutes or 1.7 minutes
1.7 minutes * 1 hour/60 minutes = .028333 hours
So, you have
0.24855 miles/0.028333 hours = 8.7725 miles/hour
(400m/74s) X (3600s/1hr) X (0.000621371192 mile/meter) = 12.09 mph
24km/h or 14.9m/h
100 meters in 9.2 seconds is 24.3 miles per hour.
A car traveling 65 miles per hour would go 65 miles in one hour. A mile is equal to 1600 meters (one kilometer). Therefore, in one hour that would equate to going 1600 meters 65 times. 65 times 1600 is equal to 104,000 meters (or 104 kilometers). And since there are 60 minutes in an hour and 60 seconds in a minute, each hour has 3600 seconds (60*60=3600). Take the 104,000 and divide it by 3600 to come up with the answer. (28 and eight ninths or 28.888888888888888888888888888888 meters per second.)
210 meters = 0.13048795 miles
i believe it is 948.2 meters/minute
200 meters in 36 seconds equates to 12.43 miles per hour.
(40 meters) per (ten seconds) is 8.94774517 miles per hour
Traveling 100 meters in 80 seconds equates to an average speed of 2.79 miles per hour.
1 Nautical mile is 1 minute of latitude. Therefore 1.5 nautical miles is 1'30" (1 minute 30 seconds)
9.77 mph
100 meters in 9.2 seconds is 24.3 miles per hour.
If you traveled 100 meters in 30 seconds, then you would be traveling at 3.333... meters per second, or 200 meters per minute, or 12 kilometers per hour (7.45 miles/hour).
A car traveling 65 miles per hour would go 65 miles in one hour. A mile is equal to 1600 meters (one kilometer). Therefore, in one hour that would equate to going 1600 meters 65 times. 65 times 1600 is equal to 104,000 meters (or 104 kilometers). And since there are 60 minutes in an hour and 60 seconds in a minute, each hour has 3600 seconds (60*60=3600). Take the 104,000 and divide it by 3600 to come up with the answer. (28 and eight ninths or 28.888888888888888888888888888888 meters per second.)
400 meters per minute is about 1/4 mile per minute.
4,000 miles = 6,437,376 meters
210 meters = 0.13048795 miles
i believe it is 948.2 meters/minute
If someone or something covers 200 meters in 23 seconds, the average speed is about 19.45162 miles per hour. To solve, look at what you have to start with. You have 200 meters per 23 seconds. That's 200meters/23seconds in "math speak" here. Every mile has about 1609.344 meters in it. You already know that each minute has 60 seconds in it, and each hour has 60 minutes in it. Here's the setup: (200meters/23seconds) x (1mile/1609.344meters) x (1 minute/60seconds) x (60minutes/1hour) = Grab your calculator and have at it. Note that all the units cancel out and you're left with miles/hours or miles over hours or miles per hour. Piece of cake.
