Long bridge

Roman walked on the bridge. When he heard the whistle, he turned and saw running Kamil at the beginning of the bridge. If he went to him, they would meet in the middle of the bridge. Roman, however, rushed and so did not want to waste time returning 150m. He continues walking, and Kamil caught up with him at the end of the bridge. How long was the bridge?

Correct answer:

x =  900 m

Step-by-step explanation:

x = a+b
a -150 = x/2
a + 2•150 = x

a+b-x = 0
2a-x = 300
a-x = -300

a = 600
b = 300
x = 900
