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.

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

So, we have $\frac {1} {3}$ foot every hour.

Answer:

$\frac {1} {3}$ foot every hour
