Help needed with linear equation word problem.

Two RSM students are standing 20ft apart and spot Mrs Rifkin. If they immediately run opposite direction with speeds of 300 ft/min and 200 ft/min, how many hours will pass until they are 3,000 ft apart?

Jason L.

20 + 300t + 200t = 3000
500t = 2980
t=596 minutes = 9.93 hours
