How many mph do you need to run four miles in 36 minutes?
4 miles in 36 minutes is a 9 minute per mile pace. So the question becomes, how many 9 minute groups are in an hour. 60/9 = 6.66 miles per hour. 4 miles in 40 minutes = 6 miles per hour. 4 miles in 24 minutes = 10 miles per hour and so on.
How much hours are in 54 minutes?
Since there are 60 minutes in an hour, we know there will be less than 1 hour in the answer. The correct answer will be a fraction. To find the answer, first convert your hour to minutes. 1 hour = 60 minutes Second, divide the minutes you started with (54) by the hour (60). You will arrive at an answer of 0.9, or converted to a fraction, 9/10 of an hour.
If a runer runs a mile in 9 minutes how fast were they running MPH?
The runner would be running at 6.67 miles per hour. This is answered by dividing 60 (minutes in an hour) by 9 (minutes it took for one mile). You are basically saying that the runner will run a mile every 9 minutes, so how many '9 minutes' (each mile ran) are in an hour.
How many km do you run if you run 9 km per hours for 15 minutes?
9km per 60 minutes (1 hour) 9000m (9km) divided by 60 minutes (1 hour) is 150m per minute 150m (per minute) x 15 minutes = 2250m per 15 minutes That gives you 2250m (2.25km) per 15 minutes at 9 km per hour :) +++ Another approach there would have been to use the simple fraction of the hour: just divide 9000metres by 4. (I.e. multiply the distance by the number of hours.) However the you way you used is important by showing the principles of such calculations.
How fast do you have to run to do a mile in 9 minutes?
