The distance between a and B is x km. A bus and a car set out from two places at the same time and went opposite each other. After meeting for four hours, the speed of the bus is per hour 50 km, for car speed

The distance between a and B is x km. A bus and a car set out from two places at the same time and went opposite each other. After meeting for four hours, the speed of the bus is per hour 50 km, for car speed


The sum of the speed of the two cars is x / 4
So the car's speed is x / 4-50



A bus and a car are going to meet each other at the same time from the two places where they are together for 1800 kilometers. After 9 hours, they meet. The speed ratio of the bus and the car is 3:2. When they meet, the bus and the car will meet
How many meters did the car travel? You need to get the answer before 7:30! There must be a formula!


The distance of the bus is 1800 * 3 / (3 + 2) = 1800 * 3 / 5 = 1080 km
The distance traveled by car is 1800-1080 = 720 km



A car and a bus are running at the same time from two places 280 kilometers apart. After two hours of meeting, it is known that the speed ratio of car and bus is 5:3
How many kilometers less does a bus travel per hour than a car?


The sum of the speed of the two cars is 280 / 2 = 140 km, so the passenger car is 140 x (3 / (5 + 3) km / h, and the car is 140 x 5 / (5 + 3) km / h. The passenger car is 140 x (5-3) / (5 + 3) = 35 km / h less than the car



A bus and a car run from two places 1200 km apart at the same time. They meet in 8 hours. The speed ratio of the bus to the car is 2:3
What is the speed of a bus and a car?


Suppose the speed of the bus is 2x,
The speed of the car is 3x
The result is: 2x * 8 + 3x * 8 = 1200
5X=150
X=30
So: the speed of the bus is: 2 * 30 = 60 km / h
The speed of the car is: 3 * 30 = 90 km / h
