1. The East and West towns are 240 km apart. A bus leaves from the East Town at 8 am and a truck leaves from the West Town at 9 am. By 12 noon, the two cars just meet at the middle point between the two towns. If the two cars leave each other from 8 am to 10 am, the two cars will stop at the middle point between the two towns, How many kilometers are there between the two cars? 2. Car a and car B drive in the opposite direction from the midpoint between the East Village and the West Village at the same time. Six hours later, car a arrives at the East Village, and car B is 42 kilometers away from the West Village. It is known that car a's speed is twice that of car B. how long is the road between the East Village and the West Village? Please do not use the equation solution, use the general formula or comprehensive formula, please write the answer of the formula
