The distance between the two berths is 212 km. Two motor ships sailed from them at the same time towards one one, which met after 4 years. The speed of one motor ship is 24 km. Find the speed of the second motor ship.

Two motor ships simultaneously left the opposite berths towards each other. Both moved for 4 hours. The speed of the first was 24 km / h, and the entire route between the two berths is 212 kilometers.
Let’s write down the general formula for finding the path:
S = V * t (where S is the path; V is the speed; t is the travel time).
Let’s find how much before the meeting in 4 hours the first motor ship passed at a speed of 24 km / h, substituting the data into the above formula:
S = 24 * 4 = 96 (km) – the first motor ship passed.
If we subtract from the entire distance the distance that the first motor ship traveled, then we find out the distance that the second motor ship traveled before the meeting:
212 – 96 = 116 (km) – the second motor ship passed.
He also moved for 4 hours. From the path formula, we can calculate the speed:
V = S: t.
Let’s find the speed of the second motor ship:
116: 4 = 29 (km / h) – speed of the second motor ship.
Answer: 29 km / h.
