A and B drive from city a to city B at the same time. Car a travels 60 kilometers per hour and car B 45 kilometers per hour Car a and car B drive from city a to city B at the same time. Car a travels 60 kilometers per hour, and car B travels 45 kilometers per hour. After 5 hours, car a encounters a bus coming face to face. Another hour later, car B also encounters the bus. How many kilometers does the bus travel per hour? (equation solution. One yuan equation)

A and B drive from city a to city B at the same time. Car a travels 60 kilometers per hour and car B 45 kilometers per hour Car a and car B drive from city a to city B at the same time. Car a travels 60 kilometers per hour, and car B travels 45 kilometers per hour. After 5 hours, car a encounters a bus coming face to face. Another hour later, car B also encounters the bus. How many kilometers does the bus travel per hour? (equation solution. One yuan equation)

If the bus speed is x, then 60 * 5 = 45 * 6 + X * 1
X=30
The bus is 30 kilometers per hour

Car a runs 90 kilometers per hour, and car B runs 60 kilometers per hour. Car a and car B start from a and B at the same time, and run in opposite directions. When passing through C, car B arrives 10 minutes earlier than car a; the next day, car a and car B start from B and a at the same time and return to their original place. When passing through C, car a arrives 1.5 hours earlier than car B?

Let C be x km away from a and Y km away from B
Y/60+1/6=X/90
Y/90+1.5=X/60
It can be calculated that: x = 150, y = 90, so the distance between AB and ab is 150 + 90 = 240 km

Two cars drive from place a to place B. car a starts 90 kilometers ahead of car B. after 4.5 hours, two cars arrive at place B at the same time. Car a travels 60 kilometers per hour to find car B

Hello
(60 × 4.5 + 90) △ 4.5 = 80 km / h
The speed of car B is 80 km / h
Hope to help you!
