Question

interactive practice: use unit rates to solve problems
tiffany is learning to read braille. she can read 225 words in 5 minutes.
how many words per minute can tiffany read?
words per minute

Explanation:

Step1: Identify the given values

Tiffany reads 225 words in 5 minutes. We need to find the number of words per minute, which is a unit rate. The formula for unit rate (in this case, words per minute) is $\text{Words per minute} = \frac{\text{Total words}}{\text{Total minutes}}$.

Step2: Substitute the values into the formula

Substitute the total words (225) and total minutes (5) into the formula: $\text{Words per minute} = \frac{225}{5}$.

Step3: Perform the division

Calculate $\frac{225}{5}$. 225 divided by 5 is 45.

Answer:

45
