Tourists

From the cottage started first group of tourists at 10:00 AM at speed 4 km/h. The second started after them 47 minutes later at speed 6 km/h. How long and how many kilometers from the cottage will catch the first group?

Result

t =  1.57 h
s =  9.4 km

Solution:

4*(t+47/60) = 6 t
s= 6t

120t = 188
s-6t = 0

s = 475 = 9.4
t = 4730 ≈ 1.566667
