1.7 m/s

Explanation:

52,000kg x 3.4 m/s= 176,800

52,000+52,000= 104,000

DIA [1.3K]

Answer:

<em>The total distance of the entire trip is 16 Km</em>

Explanation:

<u>Distance and Displacement</u>

A moving object constantly travels for some distance at certain periods of time. The total distance is the sum of each individual distance the object traveled. It can be written as:

dtotal = d1 + d2 + d3 + ... + dn

This sum is obtained independently of the direction the object moves.

The displacement only takes into consideration the initial and final positions of the path defined by the object in its moving. The displacement, unlike distance, is a vectorial magnitude and can be even zero if the object starts and ends the movement at the same point.

The described movements are 6 Km North and 10 Km West. Regardless of the speed or time taken, the total distance is:

d = 6 Km + 10 Km = 16 Km

The total distance of the entire trip is 16 Km
