Car a and car B leave each other from the two places. Car a travels 75 kilometers per hour, and car B travels 65 kilometers per hour. After 5.6 hours, they meet. How far is the distance between the two places

Car a and car B leave each other from the two places. Car a travels 75 kilometers per hour, and car B travels 65 kilometers per hour. After 5.6 hours, they meet. How far is the distance between the two places

784 km apart
Speed sum = 75 + 65 = 140 km
Distance = speed × time = 140 × 5.6 = 784 km

Car a (75KM / h) starts at 2 o'clock, then car B (85km / h) starts, meets at the midpoint, and calculates the distance between the two places

Let two cars meet in X hours
75*（2+X）=85X
X=15
The distance between the two places is 85 * 15 * 2 = 2550

Car a and car B leave each other at the same time. Car a travels 85 kilometers per hour and car B 75 kilometers per hour. They meet 4.8 hours after departure

(85+75)x4.8=160x4.8=768 km

The distance between the two places is 480 kilometers. The two cars run from each other at the same time and meet four hours later. It is known that the speed ratio of the two cars is 5:3. How many kilometers do the two cars walk each hour

A and B cars travel together every hour
480 △ 4 = 120 (km)
Car a runs every hour
120 △ (5 + 3) × 5 = 75 (km)
Car B runs every hour
120-75 = 45 (km)
