From two cities A and B, located at a distance of 135 km from each other, 2 cars drove out simultaneously

From two cities A and B, located at a distance of 135 km from each other, 2 cars drove out simultaneously in opposite directions. The speed of one is 70 km / h, the other is 90 km / h. How far will the cars be from each other in 3 hours?

1. Since cars move from two cities in different directions, let’s find the speed of their removal. To do this, let’s summarize the speed of the cars.

70 + 90 = 160 km / h vehicle removal speed.

2. Let’s find how far the cars will move in three hours of their movement. To do this, we multiply the speed of removing cars by time.

160 * 3 = 480 km

3. Let’s find at what distance at this moment these cars will be from each other. To do this, add the distance between cities to the distance that the cars will drive.

480 + 135 = 615 km

Answer: The distance between the cars will be 615 km.
