How many dollars per hour if there is 15 cent per minute?
To convert 15 cents per minute to dollars per hour, first convert cents to dollars: 15 cents is $0.15. Since there are 60 minutes in an hour, multiply $0.15 by 60. This gives you $9 per hour.
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.
