| **The rafts swam simultaneously in opposite directions. when one raft sailed 44 km / h at a speed of 4 km / h, the distance between the rafts became 66 km. At what speed was the other raft sailing?**

Let’s find how long the rafts sailed in opposite directions:

t = S1 / v1;

t = 44/4 = 11 hours.

Let’s find the distance that the second raft sailed:

S2 = S – S1;

S2 = 66 – 44 = 22 km.

Let’s find the speed of movement of the second raft:

v2 = S2 / t;

v2 = 22/11 = 2 km / h.

Check:

(v1 + v2) * t = (4 + 2) * 11 = 66 km.

Answer: the second raft was moving at a speed of 2 km / h.
