Question

Automobiles are fitted with a device that shows the distance travelled. Such a device is called an
odometer. A car is driven from New Delhi to Mumbai, the difference between the final reading
and the initial reading of the odometer is 1,550 km.
Suppose you have a road map with a scale of 1 cm representing 200 km. On this map, using the
shortest line, distance between New Delhi and Mumbai is represented by 7 cm.
Read the above passage and answer the following questions:
1. Find the magnitude of displacement between New Delhi and Mumbai with the help of this
road map.
2. What is more relevant to your journey, distance or displacement? Justify.
3. If a car travels from New Delhi to Mumbai and then returns back to New Delhi, what is the
distance covered and displacement covered for the complete journey.
please answers my questions properly

Answer 1

Answer:

1.1400km

2.displacement is more relevant (short )

3.distance =3100km

displacement=zero as initial and final positions are same

Explanation:

hope this is helpful

distance is total length between initial and final positions

displacement is the shortest distance between initial and final positions

Answer 2

Answer:

(i) 1400km

(ii). Distance

(iii) distance =3100km

displacement =0

Explanation.

(i) displacement= 7×200

=1400km

(ii) Distance because the car doesn't move in a linear motion.

(iii) Total distance=1550×2

=3100km

Displacement =0 (because the initial position and the final position is same)
