Question

A man walks 40km towards south and then turns right to walk 9km. What is the shortest distance between starting point and ending point.
50km
41km
49km
31km​

Answer 1

Answer:

41 km

Step-by-step explanation:

by Pythagoras theorem

hypotenuse^2 = (distance cover in South)^2+(distance cover in right)^2

h^2=40^2+9^2

h=√1600+81

h=√1681

h=41 km

Answer 2

Answer:

Option A 50Km

Step-by-step explanation:

Drawing the diagram according to the given information,

By using Pythagoras’ theorem, the distance between A and B = √((40)2 + (30)2) = √2500 = 50 m

Hence, “50” is the correct answer
