Sebastian

From Kovalov Sebastian walks at 6 km / h started at 8:00 in the direction of Kuty. From Kuty, the godfather is driving at 50 km/h and started at 8:30. The distance is 24 km. When and where grandfather will take Sebastian to the car.

Result

t = 8:54 h
s =  5.357 km

Solution:

s = 6(t-8.00)
d = 50(t-(8+30/60))
s+d = 25

s-6t = -48
60d-3000t = -25500
d+s = 25

d = 275/14 ≈ 19.642857
s = 75/14 ≈ 5.357143
t = 249/28 ≈ 8.892857
