astra-53 [7]

Answer:

9000 metres

Step-by-step explanation:

He went on a 54 km hike. First, we have to find this distance in metres.

1 km = 1000 m

54 km = 54 * 1000 = 54000 m

He divided the distance evenly over 6 days.

To find how many metres he walked each day, we divide the total distance he hiked by the number of days spent. That is:

54000 / 6 = 9000 metres

He walked 9000 metres each day.
