Two boats sail towards each other, the speed of 1 boat is 18 km / s. the speed of 2 boats is 6 km more.

Two boats sail towards each other, the speed of 1 boat is 18 km / s. the speed of 2 boats is 6 km more. now there are 168 between them at what distance will they be in 3 hours? how long will they meet?

Let’s find the speed of the second boat:
18 + 6 = 24 (km / h).
Let’s find the distance each boat sailed in 3 hours:
18 * 3 = 54 (km) – the first boat sailed;
24 * 3 = 72 (km) – the second boat sailed;
Let’s find at what distance the boats will be in 3 hours:
168 – (54 + 72) = 168 – 126 = 42 (km).
Let’s find the total speed of the boats:
18 + 24 = 42 (km / h).
Let’s find out how many hours the boats will meet:
168/42 = 4 (h).
Answer: in 3 hours the distance between the boats will be 42 km, boats will meet in 4 hours.
