Manuel traveled 31 hours nonstop to Mexico, a total of 2,300 miles. He took a train part of the way, which averaged 80 mph, and then took a bus the remaining distance, which averaged 60 mph. How long was Manuel on the train?

rate   *     time  = distance

 

 

train time = t

bus time = b   =  31 hrs - t

 

80 * t         +      60 (31 - t)      =   2300

80t            +      1860  - 60 t     = 2300          solve for 't'   the train time
