The own speed of the ship is 28.7 km / h and its speed against the river flow is 25.6 km / h. What is the distance the motor ship will sail if it sails 5.5 hours downstream
1. Find the speed of the river.
28.7 – 25.6 = 3.1 kilometers.
2. Let’s determine at what speed the motor ship sails per hour along the river.
28.7 + 3.1 = 31.8 kilometers.
3. Let’s calculate how many kilometers the motor ship will sail in 5.5 hours downstream.
31.8 * 5.5 = 174.9 kilometers.
Answer: The motor ship will sail along the river for 174.9 kilometers.
