In a co-flowing (same-direction) heat exchanger, 1 kg/s air at 500Kflows into one channel and 2 kg/s

Question:

In a co-flowing (same-direction) heat exchanger, 1 kg/s air at 500Kflows into one channel and 2 kg/s air flows into the neighboring channel at 300 K. If it is infinitely long, what is the exit temperature? Sketch the variation of T in the two flows.
