Call of Duty

Game Call of Duty in CTF (Capture the Flag) opposes the British and the Germans, whose bases are 15 km apart. A German soldier stole the British flag and hid it with it in a secret place between the bases. If the British soldiers set out at a speed of 14 km/h and at the same time, if German troops were set at a speed of 18 km/h, both camps would collide in a secret place. How many kilometers from the German base does a German soldier with a flag hide?

Result

x =  8.438 km

Solution:


14t + 18t = 15
x = 18t

32t = 15
18t-x = 0

t = 1532 = 0.46875
x = 13516 = 8.4375
