Two boats departed from two piers at the same time towards each other, which met after 3 hours. The speed of the 1st boat is 15 km / h, the speed of the 2nd boat is 18 km / h. Find the distance between the marinas.
1. Let’s calculate the distance that the boat covered in 3 hours, which was going at a speed of 15 kilometers per hour.
3 * 15 = 45 kilometers.
2. Determine the distance traveled by the second boat, if the time and speed of the boat are known.
3 * 18 = 54 kilometers.
3. Find out the distance between the marinas from which two boats left.
45 + 54 = 99 kilometers.
Answer: The distance between the marinas is 99 kilometers.
