Question: Natalia is riding a bicycle for the cycling competition. On Monday she rode 40 kilometers and on Tuesday 50 kilometers. On Wednesday she rode 50% fewer kilometers than the day before. On Thursday she rode as many as the sum of the kilometers from Monday and Wednesday. How many kilometers did Natalie ride in total? Think carefully first, then make a decision:
On Wednesday she covered half of the distance from Tuesday, so 50 / 2 = 25 kilometers. On Thursday she rode 40 + 25 = 65 kilometers. In total, Natalia rode 40 + 50 + 25 + 65 = 180 kilometers. So the answer is 180.
