Final answer:
To find the total distance Nina traveled, simply add the distance to her grandmother's house (32 miles) and the distance to her friend's house (17 miles), which equals 49 miles.
Step-by-step explanation:
Nina's total travel distance can be calculated by adding the distance she traveled to her grandmother's house to the distance she traveled to her friend's house. To calculate the total distance, you sum the two individual distances: 32 miles plus 17 miles.
Add the miles: 32 miles + 17 miles = 49 miles
