Question

A truck moves 60 kilometers east from point A to point

b. At point B, it turns back west and stops 15 kilometers away from point
a. What are the total distance and total displacement of the truck?

Answer 1

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 2

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

Step-by-step 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.
