Inez stretched for 19 mins before jogging on a trail. It took her 5 minutes to run each lap around the trail. Write an equation to represent the relationship between the number of laps, l, and time, t.
1 lap= 15 min
2 lap = 30 min
3 lap=45 min
4 lap = 60 min
t = 19+ 15 L
I think your teacher will want the 19 included in the total time.
If not, then t = 15L
To write an equation to represent the relationship between the number of laps, l, and time, t, we need to analyze the given information.
First, let's break down the time Inez spent on stretching and running. We know that Inez stretched for 19 minutes before starting to run. After that, it took her 5 minutes to complete each lap around the trail.
So, the time spent on running depends on the number of laps completed. Each lap takes 5 minutes, and the number of laps can be represented by the variable "l". Therefore, the time spent running, in minutes, can be calculated as:
Time spent running = 5 * (number of laps) = 5l
Additionally, we need to consider the time spent on stretching. Inez stretched for 19 minutes, regardless of the number of laps she completed. Hence, the total time spent, in minutes, can be calculated as:
Total time = Time spent stretching + Time spent running = 19 + 5l
Therefore, the equation to represent the relationship between the number of laps, l, and time, t, is:
t = 19 + 5l
