Two motor ships departed simultaneously from two piers, the distance between which is 4500 m, in opposite directions.

Two motor ships departed simultaneously from two piers, the distance between which is 4500 m, in opposite directions. The speed of one motor ship is 550m per minute, and the other is 150m per minute less. What is the distance between them in 3 hours.

1. Let’s find how many meters in one minute the second motor ship sails, if it is said that its speed is 150 meters per minute less than the speed of the first motor ship.

550 – 150 = 400 meters.

2. Let’s calculate the speed of removal of motor ships per minute.

550 + 400 = 950 meters.

3. Let’s determine how many kilometers in 1 hour they pass together.

950 * 60 = 57,000 meters.

57,000/1000 = 57 kilometers.

4. Let’s find out at what distance they will be from each other in 3 hours, if it is said that initially the distance between them was 4500 meters.

4500 m = 4500/1000 = 4.5 kilometers.

57 * 3 + 4.5 = 175.5 kilometers.

Answer: There will be a distance of 175.5 kilometers between the ships.
