Before completing the task, it will be convenient to convert the length of the river to meters. There are 1000 m in a kilometer. Therefore, 2 km 750 m = 2 * 1000 + 750 = 2750 m.To find the size of the inflow, subtract the difference of 900 m from the length of the river.
We decide:
2750 – 900 = 1850 m
Once in the conditions the length of the river was indicated in km and meters, then we translate the result obtained:
1850 m = 1000 m + 850 m = 1 km 850 m
Answer: the length of the tributary is 1 km 850 m.
