Final answer:
To determine the total time Mrs. Coloma walked her dog Moana, we use the equation t = 30 + m, where t represents the total time in minutes and m represents the additional minutes walked after school.
Step-by-step explanation:
The question involves creating an equation that represents the total amount of time Mrs. Coloma spent walking her dog, Moana. The equation should include the time spent walking before and after school. We are given that the time spent walking before school was 30 minutes. Let m represent the additional minutes Mrs. Coloma walked Moana after school. The total time spent walking, represented by t, will be the sum of both these durations.
The equation representing the total time spent walking Moana is:
t = 30 + m
This equation can be used to calculate the total walking time once the value of m is known.
