The boat sailed for 2 hours at a speed of 35 km / h. Then he increased the speed by 3 km / h and swam for the same number of hours. Which way did the boat go?
1. Let’s calculate what distance the boat sailed in 2 hours, moving at a speed of 35 km per hour.
2 * 35 = 70 km per hour.
2. Find out the speed of the boat when he increased it by 3 km per hour.
35 + 3 = 38 km per hour.
3. Let’s calculate what distance the boat covered, moving at a speed of 45 km per hour, if it is known that it also sailed for 2 hours.
38 * 2 = 76 km.
4. Now we find out how many kilometers the boat sailed.
70 + 76 = 146 km.
Answer: The distance covered by the boat is 146 km.
