Four runners ran a combined total of 195 miles last week. Katarina ran 51 miles. Tomas, Tyler, and Harriet all ran the same distance. How many miles did Harriet run? Give me reasons, before answering the question
195 - 51 = 144 = miles the 3 runners ran. 144 / 3 = 48 miles. Harriet ran 48 miles. So the final answer is 48.
