To find the answer to that, you have to see how many numbers are between 13 and 31. There are 18 numbers between 13 and 31. Divide 18 by 2 and you will get the number halfway. 9 is halfway between 13 and 31. So, add 9 to 13 and you get 22.

The answer is 22.

1/4 foot every 3/4 hour how many feet in one hour

RUDIKE [14]

For this case we propose a rule of three:

$\frac {1} {4}$ foot -------------> $\frac {3} {4}$ hour

x -----------------------------------> 1 hour

Where "x" represents the amount of foot in one hour.

$x = \frac {1 * \frac {1} {4}} {\frac {3} {4}}\\x = \frac {\frac {1} {4}} {\frac {3} {4}}\\x = \frac {4 * 1} {3 * 4}\\x = \frac {4} {12}\\x = \frac {1} {3}$
