The boat sailed for 1.5 hours at a speed of 34 km / h and 2.5 hours at a speed of 30 km / h. Find its average speed during the movement.
1. Let’s calculate how many kilometers a boat passed in 1.5 hours moving at a speed of 34 kilometers per hour.
1.5 * 34 = 51 kilometers.
2. We find the distance covered by the boat in 2.5 hours if it is said that its speed was 30 kilometers per hour.
2.5 * 30 = 75 kilometers.
3. Find out the entire route covered by the boat.
51 + 75 = 126 kilometers.
4. Determine the time during which he swam 126 kilometers.
1.5 + 2.5 = 4 hours.
5. Find the average speed.
126/4 = 31.5 kilometers.
Answer: The average speed of the boat was 31.5 kilometers per hour.
