Sally has been measuring a flower for a science project. The flower has grown (1)/(2) of a centimeter each day and grown a total of 2 centimeters taller. How many days has Sally been measuring this flower? square days

To find out how many days Sally has been measuring the flower, we need to divide the total growth of the flower by the daily growth rate.<br /><br />Given:<br />- The flower has grown $\frac{1}{2}$ of a centimeter each day.<br />- The flower has grown a total of 2 centimeters taller.<br /><br />We can set up the equation as follows:<br />\[ \text{Total growth} = \text{Daily growth rate} \times \text{Number of days} \]<br /><br />Substituting the given values:<br />\[ 2 \text{ cm} = \frac{1}{2} \text{ cm/day} \times \text{Number of days} \]<br /><br />To solve for the number of days, we divide both sides of the equation by $\frac{1}{2}$ cm/day:<br />\[ \text{Number of days} = \frac{2 \text{ cm}}{\frac{1}{2} \text{ cm/day}} \]<br /><br />Simplifying the division:<br />\[ \text{Number of days} = 2 \text{ cm} \times \frac{2}{1} \text{ days/cm} \]<br />\[ \text{Number of days} = 4 \text{ days} \]<br /><br />Therefore, Sally has been measuring the flower for $\boxed{4}$ days.
