liz is taking guitar lessons and practices every night. yesterday, she played a total of 40 chords in 8 minutes. today, she will play chords for 5 minutes. if she plays at the same rate, how many chords will liz play today? chords
Answer
Explanation:
Step1: Calculate the rate of playing chords
First, find the rate of playing chords per minute. Rate = $\frac{\text{Number of chords}}{\text{Time}}$. Given she played 40 chords in 8 minutes, so the rate $r=\frac{40}{8}=5$ chords per minute.
Step2: Calculate the number of chords today
Since the rate is 5 chords per minute and she plays for 5 minutes today, the number of chords $n = r\times t$. Substitute $r = 5$ and $t = 5$ into the formula, we get $n=5\times5 = 25$ chords.
Answer:
25
