Jennifer wants to go to a museum. There is one 5 miles away from her home and one 15 miles away. If Jennifer goes to both museums on two separate days, how many miles total will she travel? Let's answer step by step:
Jennifer's home is 5 miles away from the first museum, so the round trip back and forth is 5 miles there + 5 miles back = 10 miles altogether. On another day Jennifer goes to a museum 15 miles away + 15 miles to return home = 30 miles total. Combined, Jennifer travels 10 miles on the first day + 30 miles on the second day = 40 miles Jennifer travels total. The answer: 40.
