3.15 minutes which is extremely fast
About 21 minutes 47 seconds.
The runner covered a total of 3520 yards (2 miles = 3520 yards).
No. If there were any way to convert between miles and minutes, then you'd be able to figure out how many seconds high your house is, and how many yards of sleep you had last night.
5.3 seconds for 100 yards.
0.00057 hours approx = 0.034 minutes or 2.05 seconds.
This is a problem where you have to convert to similar units before you can solve. It is easiest to covert miles into yards (otherwise we'd be dealing with a lot of decimals). 1 mile = 5,280 feet and 3 feet = 1 yard. Therefore: 3 miles/1 hour * 5280 feet/1 mile * 1 yard/ 3 feet = 5,280 yards/hour 3 mph = 5,280 yards/hour Now that units are similar (you are running at 5,280 yards/hour), we can easily figure out how long it will take to run 150 yards. 5280 yards/ 1 hour = 150 yards/ X 5280X = 150 X = .028409 hours This answer is a bit strange so let's convert it to minutes. We know 1 hour = 60 minutes, so: .028409 hours * 60 minutes/1 hours = 1.70454 minutes If you want to go one step further and convery the .70454 minutes into seconds: .70454 minutes * 60 second/1 minute = 42.27 seconds Our answer then is: if you run at 3 mph, it would take 1 minute 42.3 seconds to run 150 yards.
To convert yards per second to miles per hour, first convert yards to miles and seconds to hours. There are 1760 yards in a mile and 3600 seconds in an hour. Therefore, 19 yards in 2.5 seconds is equal to approximately 44.6 miles per hour.
80.25 yards
To find out how many mph is 100 yards in 11 seconds: First, convert 100 yards to miles (100 yards = 0.057 miles). Next, calculate the speed by dividing the distance (in miles) by the time (in hours) - 0.057 miles / (11 seconds / 3600 seconds) = 19.64 mph.
There are 1760 yards in one mile. Therefore, 5 miles per hour is equal to 5 x 1760 = 8800 yards per hour. To travel 400 yards at 5 miles per hour would take 400/8800 x 60 = 2.72 recurring (that is, 2.727272...) minutes or 2 minutes 43.63 recurring (that is, 2 minutes 43.636363...) seconds.
