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.
pls answer correct

Answer 1

Explanation:

1 the magnitude of displacement is 1400 km.

2 the more relevant to my journey is distance because car uses odometer to measure.

3 ifthe car travels from new delhi to mumbai and then back to delhi total distance covered will be 1550+1550 = 3100km

and the displacement will be 0 because initial and final position are same.

plz mark my answer as branlist.
