Two cyclists left one city simultaneously in opposite directions. Their speed is 15 km / h and 17 km / h. Which path each cyclist traveled when the distance between them became 128 km.
1) 15 km / h + 17 km / h = 32 km / h – the average speed of cyclists was obtained.
2) 128km ÷ 32km / h = 4h – the time during which each cyclist moved away from each other.
3) 15km / h × 4h = 60km – distance of the first cyclist
4) 17km / h × 4h = 68km – distance of the second cyclist
