The boat and raft are sailing along the river in the same direction. The boat sails at a speed of m km / h, and the raft – at a speed of 2 km / h. What is the distance between the boat and the raft in 45 minutes if m = 10?

1) 10-2 = 8 (km / h) – distance speed
45min = 45 / 60h = 3 / 4h = 0.75h
2) 8 * 0.75 = 6 (km) – this is the distance the boat will move from the raft in 45 minutes
Answer: 6km
