Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train
A heading towards station A, and train B heading towards station B. Train A reaches station A after 3 h. Train B reaches station B after 214 h. Station A and Station B are 420 mi apart. What is the rate of the trains?
So you want to make it: total distance (d) = rate (r) × total time (t), solving for r: r = d / t r = (420mi) / (3h+214h), r = 420mi / 217h r = 1.935mi/h = 1.94mi/h
