Train from Brno

First train started from Brno at 8 am at 60 km per hour. Second train started from Opava at 7 o'clock at the speed of 40 kilometers per hour. In how many hours and how far from cities trains meet when the distance of cities is 200 kilometers.

Result

t = 9:36 h Wrong answer
b =  96 km
o =  104 km

Solution:


b+o = 200
b = 60(t-8)
o = 40(t-7)


b+o = 200
b = 60•(t-8)
o = 40•(t-7)

b+o = 200
b-60t = -480
o-40t = -280

b = 96
o = 104
t = 485 = 9.6
