Question

some antarctic explorers heading due south toward the pole travel 50. km during the first day. A sudden snow storm slows their progress and they move only 30. km in the second day. With plenty of rest they travel the final 65 km the last day and reach the pole.What was the explorers' displacement?

Answer 1

Answer:

145km

Explanation:

The displacement is a vector quantity, it tells how far away from a point a distance or a destination is

given that the distance covered are

50. km, 30. km, and 65 km

the displacement is expressed as

= 50+30+65

=145km

We actually performed straight addition because in all the movement the antarctic explorers did not record any deviation from the initial direction, hence they maintained a linear movement from the beginning to the end
