A whale swims due east for a distance of 4.2 km, turns around and goes due west for 3.0 km, and finally turns around again and heads 1.8 km due east.
What is the total distance traveled by the whale?
d = 4.2 + 3 + 1.8 = 9km.
A body travels 20m due north 10m west and 30 m south west calculate displacement.solve by vector method
To find the total distance traveled by the whale, we can add up the distances it traveled in each direction.
Distance traveled east: 4.2 km + 1.8 km = 6.0 km
Distance traveled west: 3.0 km
Now, let's add these distances together:
Total distance traveled = Distance traveled east + Distance traveled west
Total distance traveled = 6.0 km + 3.0 km = 9.0 km
Therefore, the total distance traveled by the whale is 9.0 km.
To find the total distance traveled by the whale, we need to add up the distances traveled in each segment.
Segment 1: The whale swims due east for a distance of 4.2 km. This is straightforward. Therefore, we add 4.2 km to the total distance.
Total distance: 4.2 km
Segment 2: The whale turns around and goes due west for 3.0 km. Since the whale is moving in the opposite direction, we subtract 3.0 km from the total distance.
Total distance: 4.2 km + (3.0 km) = 7.2 km
Segment 3: The whale turns around again and heads 1.8 km due east. Similar to Segment 1, we add 1.8 km to the total distance.
Total distance: 7.2 km + 1.8 km = 9.0 km
Therefore, the total distance traveled by the whale is 9.0 km.
