Question

A whale swims due east for a distance of5 km, turns arond and goes due west for 1.8 km and finally turns again and head 1.2 km due east.what is the distanse and displacement of the whale.
step by step explanation ☺​

Answer 1

Answer:

5-1.8+1.2

= 4.4 displacement

5+1.8+1.2

= 8 total distance

Answer 2

Distance

Whale first swims due east for distance of 5 km.

It turns around in west for 1.8 km.

It heads to east for 1.2 km.

Distance: Distance is the total movement of an object without any regard to direction.  It is scalar quantity.

Displacement: Displacement is defined as the change in position of an object. It is vector quantity.

Distance $= 5+1.8+1.2=8 \ km$

Displacement $=5-1.8+1.2=4.4 \ km$

Note: The scenario is well explained through a picture attached, all way should be on same line ideally, but to understand small distance between lines are given.
