Two swallows flew from the nest simultaneously in opposite directions. After 20 s, the distance between them was 680 m. What is the speed of one of the swallows if the other flew at a speed of 16 m / s?
1. Let’s find out how many meters the swallow flew away in 20 seconds, the speed of which is 16 m / s.
20 * 16 = 320 meters.
2. Let us define the path of another swallow, if it is said that their total path is 680 meters.
680 – 320 = 360 meters.
3. Let’s calculate with what speed it flew.
360/20 = 18 meters.
Answer: The speed of the swallow is 18 meters per second.
