Lani and her family went to Bandung by bus. The distance from Jakarta to Bandung is 130 km. The bus has covered a distance of 50,000 m from Jakarta to Bandung. How many km does the bus have to travel?

Answer 1

The bus has covered a distance of 50,000 m, which is equal to 50 km (1 km = 1000 m). Subtracting this distance from the total distance from Jakarta to Bandung (130 km), we find that the bus still needs to travel 130 km - 50 km = <<130-50=80>>80 km. Answer: \boxed{80}.
