Question

a man start walking and cover 3 meters in north direction then he turn right and cover 4 metre. from this point again he walks north direction and covered 3 meters distance then he take another right and cover 4 metre distance

find the total distance travel and total displacement​

Answer 1

Explanation:

Let north, east be represented by N, E.

According to question:

• ⇒ 3m in North = 3N
• ⇒ 4m in East(right) = 4E
• ⇒ 3m in North = 3N
• ⇒ 4m in East(right) = 4E

Total displacement = 3N + 4E + 3N + 4E

• ⇒ 6N + 8E

As North and east are at right angle to each other, So, we will use Pythagoras theorem to find displacement

• Displacement = √6² + 8² = 10
• Displacement is 10 m

• Distance = 6 + 8 = 14 m

Answer 2

Answer:

A goes 3 Km North and 4 Km East then.

B goes 5 Km West and then 3 Km North.

So, B is 5 km far from the point where A turned right and A is 4 km far from t.
