On a highway, the total number of vehicles passing is 300. If the number of cars on the highway is twice the number of trucks, find out the total number of trucks on the highway? Let's answer step by step:
If we assume that the number of trucks on the highway is t, the number of cars on the highway will be 2 * t = 2t. The total number of cars and trucks on the road is 2t + t = 300. The number of vehicles on the road is 3t = 300. The are t = 300 / 3 trucks on the highway. This means there are t = 100 trucks on the road. The answer: 100.
