Question

Bailey has 45 min to exercise. It take Bailey 3 min to jog around the track and 5 min to stretch. She jogs 6 laps around the track and stretches 2 times Write and evaluate an algebraic expression to find the amount of time Bailey has left. Use j for the number of laps jogged and s for the number of times she stretched. Show the work for me please.

Answer 1

Therefore, Bailey has 17 minutes left for exercise.

Explanation:

To find the amount of time Bailey has left for exercise, we can subtract the time spent jogging and stretching from the total time she has for exercise.

Let's break down the time spent on each activity:

Time to jog around the track per lap = 3 minutes

Number of laps jogged = 6 laps

Total time spent jogging = 3 minutes per lap × 6 laps = 18 minutes

Time spent stretching per session = 5 minutes

Number of times Bailey stretched = 2 times

Total time spent stretching = 5 minutes per session × 2 times = 10 minutes

Now, let's write an algebraic expression to find the amount of time Bailey has left (t):

t = Total time for exercise - (Time spent jogging + Time spent stretching)

t = 45 minutes - (18 minutes + 10 minutes)

t = 45 minutes - 28 minutes

t = 17 minutes

Therefore, Bailey has 17 minutes left for exercise.
