Question

Answer the given with explanation

Answer 1

Answer is 5 km , 3km east and 4km south ( right of East) if we join starting and ending point shortest distance is the hypotenuse of a right angle triangle with sides 3 and 4 , so hypotenuse = ✓ 3 squared + 4 squared ( Pythagoras theorem ) so it's 5

Answer 2

Answer is 5km as he travelled to the bus stop which is 3km away in the east and turned right to school 4km away.
by this we will see a triangle with base and perpendicular as 3 & 4
By Pythagoras theorem,
$\sqrt{ {3}^{2} + {4}^{2} } = shortest \: distance \\ \sqrt{9 + 16} = \sqrt{25} = 5km$
thus shortest distance is 5 km
