1. Car a and car B come from both places at the same time. Car a travels 70 kilometers per hour, while car B travels 85 kilometers per hour. When they meet, car B exceeds the midpoint by 60 kilometers. How far is the distance between the two places? 2. The school organizes a spring outing. The first car travels 30 kilometers per hour and starts at 7 am. The second car starts at 1 pm. The speed is 40 kilometers per hour. As a result, the two cars arrive at the same time. How far is it from the school to the scenic spot?

one
When they meet, B has more lines than a = 2 * 60 = 120 km
Encounter time = 120 / (85-70) = 8 hours
Distance = 8 * (85 + 70) = 1240 km
2．
When the second car starts, the first car runs 30 * 1 = 30 km
The second trip time = 30 / (40-30) = 3 hours
Distance = 3 * 40 = 120 km
