Two boats simultaneously departed from the pier in opposite directions. The speed of the first boat was 25 km / h. At what distance from each other they will be in 4 hours, if the second boat covered 48 km in 2 hours.

Let’s solve the task of actions with explanations.
1) 25 * 4 = 100 kilometers – the distance that the first boat sailed at a speed of 25 kilometers per hour in 4 hours of its movement;
2) 48: 2 = 24 kilometers per hour – the speed of the second boat if it covered 48 kilometers in two hours;
3) 24 * 4 = 96 kilometers – the distance that the second boat sailed at a speed of 24 kilometers per hour in 4 hours of its movement;
4) 100 + 96 = 198 kilometers from each other two boats will be in 4 hours.
Answer: 198 kilometers.
