Answer:

  • The train does not go the same distance each minute.
  • Approximately  6 minutes.

--------------------------------------------

The distance traveled in each minute is a speed.

Find the speed per min for each distance:

  • 9/3 = 3 km/min,
  • 12/4 = 3 km/min,
  • 18/9 = 2 km/min.

Since the speed is not same over the total distance, the first choice is correct.

Find the average speed over the given distance:

  • (9 + 12 + 18)/(3 + 3 + 2) = 39/8 = 4.875 km/min

Find the predicted time to travel 30 km:

  • 30 / 4.875 ≈ 6.15 min
