From two piers, the distance between which is 132 km, in how many hours the boats will meet if the speed of the first is 30, which is 5/6 of the speed of the second boat.
The speed of the first boat is known from the condition of the problem, expressed as an ordinary fraction 5/6 of the speed of the second boat. Find the speed of the second boat:
30/5/6 = 30/5 * 6 = 36 (km / h).
The boats were moving towards each other, we find the speed of their approach:
30 + 36 = 66 (km / h).
We find the time after which the boats will meet:
132/66 = 2 (h).
Answer: the boats will meet in 2 hours.
