Two boats departed from the pier simultaneously in opposite directions. The speed of the first is 32 km / h, the second is 4 km / h less. How long will the distance between them be 180 km?

1) 32 – 4 = 28 (speed of the second boat).

2) 32 + 28 = 60 km / h (speed of convergence of two boats).

Since we know distance and time, we can find the speed:

3) 180: 60 = 3 hours (after this time the distance between the boats will be 180 km).

Answer: 180 kilometers.
