At 7 o’clock a boat and a motor boat sailed towards each other from two piers located at a distance of 510 km. The meeting took place at midnight on the same day. The boat went at a speed of 19 km / h. How fast was the boat going? At what distance from each other were the boat and the boat 3 hours after the meeting?

The speed of the boat is x, then x + 19 is the total speed with which the boat and the boat are moving towards.
Let’s determine the time of movement of the boat and boat before the meeting:
24 – 7 = 17 (hour).

Let’s compose and solve the equation:
(19 + x) * 17 = 510;
19 + x = 30;
x = 11.

Let’s determine the overall speed of the boat and boat:
19 + 11 = 30 (km / h).

Let’s find the distance at which the boat and the boat were located 3 hours after the meeting:
30 * 3 = 90 (km).

ANSWER: The boat speed is 11 km / h. The boat and the boat were at a distance of 90 km from each other 3 hours after the meeting.
