Question

A truck moves 60 kilometers east from point A to point

Answer 1

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.

Answer 2

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 .
