AWhat are the total distance and total displacement of the truck?

Verified Answer :

a).  The truck's distance covered for the trip is

                       (60) + (60 - 15)  =  105 kilometers .

b).  Its displacement for the whole trip is the distance
and direction from the start-point to the end-point.

                          15 kilometers east .

Answer:

The total distance and total displacement of the truck are 105 km and 15 km in east.

Explanation:

Given that,

A truck moves 60 Km east from point A to point B.

At point B , it turns back west and stop 15 km away from point A.

We need to calculate the total distance

\(d= d_{A}+d_{B}\)

Put the value into the formula

\(d =60+45\)

\(d=105\ km\)

We need to calculate the displacement of the truck

Using formula of displacement

\(D=x_{A}-x_{B}\)

Put the value into the formula

\(D=60-45\)

\(D=15\ km\)

Hence, The total distance and total displacement of the truck are 105 km and 15 km in east.
