Tourists

From the cottage started first group of tourists at 10:00 AM at speed 4 km/h. The second started after them 39 minutes later at speed 6 km/h. How long and how many kilometers from the cottage will catch the first group?

Result

t =  1.3 h
s =  7.8 km

Solution:


4*(t+39/60) = 6 t
s= 6t

120t = 156
s-6t = 0

s = 39/5 = 7.8
t = 13/10 = 1.3

Calculated by our linear equations calculator.







Leave us a comment of example and its solution (i.e. if it is still somewhat unclear...):
