A train covers 2 times less distance per hour than a car. How many kilometers per hour will

A train covers 2 times less distance per hour than a car. How many kilometers per hour will the train travel if the sum of the speeds of it and the car is 150 km / h?

The solution of the problem:

1) From the conditions of this problem, we know that a train travels a distance two times less in an hour than a car. In other words, a train moves at half the speed of a car. Let’s write down:

x is the speed of the train;

x * 2 – vehicle speed.

2) The speed of the train and car together is 150 km / h. Let’s make an equation and find the unknown x:

x + 2x = 150;

3x = 150;

x = 150/3;

x = 50;

x = 50 km / h – train speed.

3) Find out the train route in 1 hour:

50 * 1 = 50 kilometers.

Answer: The train will travel 50 kilometers in an hour.
