The train traveled 720 km, and for 6 hours it went at a speed of 80 km / h, and the remaining distance at a speed of 60 km / h. How long was the train on the way?

Let’s determine the length of the path covered by the train in six hours, if its speed was 80 km / h.
80 × 6 = 480 kilometers.
Determine the length of the remaining track section if the length of the entire route is 720 kilometers.
720 – 480 = 240 kilometers.
Let’s determine how much time the train spent on the remaining section of the track if its speed was 60 km / h.
240: 60 = 4 hours.
Determine the time taken for the entire journey.
4 + 6 = 10 hours.
Answer: the train was on the way for 10 hours.
