To calculate minutes per mile, use the mathematical formula for rate (rate = distance/time). You need to know the distance traveled and the amount of time it took to travel that far.
Know MoreMake sure this measurement is in exact miles using standard form (no fractions). For example, if the distance is 10 1/2 miles, it should be written as 10.5.
This figure should be converted into minutes if it is not already. Multiply the number of hours by 60 (the number of minutes in an hour) to convert into minutes. If the time was 2 hours, you would multiply 2 by 60, which equals 120 minutes.
Divide the distance in miles by the time in minutes. For this example, 10.5 miles / 120 minutes = 0.0875 minutes per mile.
Calculate the sum of an arithmetic sequence with the formula (n/2)(2a + (n-1)d). The sum is represented by the Greek letter sigma, while the variable a is the first value of the sequence, d is the difference between values in the sequence, and n is the number of terms in the series.
Full Answer >To calculate the area of a structure or section of land mass in square miles, use the formula for area of the section's shape with the dimensions, such as length, width, and radius, in miles. Not all sections of land or buildings have a simple shape, in which case the section should be divided up into simple shapes as well as possible to get an exact answer or a good estimate.
Full Answer >It is easy to find the inverse of a matrix in MATLAB. Input the matrix, then use MATLAB's built-in inv() command to get the inverse.
Full Answer >Mechanical advantage is calculated differently depending on the type of simple machine being used. In general, mechanical advantage is a ratio of the force exerted by the machine to the force applied to the machine.
