Towns A and B are 400 miles apart. If a train leaves A in the direction of B at 50 miles
per hour, how long will it take before that train meets another train, going from B to A,
at a speed of 30 miles per hour?
from A :50/hour. *x(hour) From B : 30/hour *x(hour) 50 *x +30 *x =400 80 *x=400 x=5(hour) Then the train from A will make 50 *5=250 miles (These is fisik)
