Question

From his house Shyam drives his car 12 km north for 10 minutes. He stops for 30 minutes at a restaurant and has lunch. Then he drives 5 km east in 8 minutes. What was the magnitude of his displacement?

Answer 1

Answer:

13 kms in north-east direction.

Step-by-step explanation:

The axis of North and east are at $90^0$

This allows us to use the Pythagoras formula to solve the question. There is no need to use the time given in this question, unless you want to fine the velocity.

$\sqrt{12^2 + 5^2} = D$

$D = \sqrt{169}$

$D = 13 kms$

And hence, your answer. Hope it helped
