Question

A mountain climber is slowly making his way up a steep path over difficult terrain. Each day he climbs 3 kilometres, however by the time he wakes up each morning he has somehow slipped backwards by 2 kilometres over the course of the night.

If the path is 30 kilometres long, how many days will it take him to reach the end?

Answer 1

Answer:

30 days because the total displacement is 1km(3km-2km)
