Algebra Passenger Train Question

Question

A passenger train leaves a railway station at 12:00 pm and travels 3 hours on the Northbound tracks. A second passenger train leaves the same railway station at 12:45 pm and travels 2 hour and 15 minutes on the Southbound tracks at a speed 20 kilometers per hour faster than the first train. At 3:00 pm the two trains were 360 kilometers apart. How fast was each train traveling?

A. Define variables to represent the unknowns and setup the necessary equations to answer the question

B. Algebraically solve the equation you created and express your final answer using a complete sentence and appropriate units.

Answer 1

60 and 80 km/hr or kph

3(60) = 180

2 1/4 x 80 = 180

180 + 180 = 360

Answer 2

60 and 80 km/hr or kph

3(60) = 180

2 1/4 x 80 = 180

180 + 180 = 360
