Final answer:
The expressions representing the time Eve trained for a triathlon are 10(m + 20) minutes for morning workouts and 10(m + 30) minutes for afternoon workouts. The total training time over 10 days is the sum of these expressions.
Step-by-step explanation:
The student, Eve, is training for a triathlon and has a workout schedule that includes two workouts each day for 10 days. To calculate the total time spent training, we consider both her morning and afternoon workouts. For her morning workouts, she bikes for m minutes and runs for 20 minutes, while for her afternoon workouts, she also bikes for m minutes and runs for 30 minutes.
Therefore, the expression for the total time spent in each morning workout is (m + 20) minutes, and for each afternoon workout is (m + 30) minutes. To find the total training time over the 10 days, these expressions need to be multiplied by the number of days she trained, which is 10.
The expressions representing the total time Eve trained for 10 days are:
- Morning workouts: 10(m + 20)
- Afternoon workouts: 10(m + 30)
The overall total training time is the sum of the morning and afternoon workout totals, which is: 10(m + 20) + 10(m + 30).
