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) Find the distance that the boat sailed at a speed of 35 km / h: 35 2 = 70 (km);
2) Find out the increased speed of the boat: 35 + 3 = 38 (km / h);
3) Let’s calculate the distance covered by the boat with an increased speed: 38 · 2 = 76 (km);
4) Determine the entire distance that the boat sailed: 70 + 76 = 146 (km).
Answer: the boat covered 146 km in total.
