Question

Rita goes 12km towards east frin a point A to point B. From B She moves 5km towards north to point C. How far is she from starting point

Answer 1

Answer:

Distance starting and ending point  = AC = 13 km

Step-by-step explanation:

Distance between A and B = 12 km

Rita turned from north to east, so degree turned = 90

Distance between B and C = 5 km

AB, BC, AC from a right angled triangle where,

AB = 12km

BC = 5km

Angle ABC = 90 degree

By Pythagoras property,

AC square = AB square + BC square = 12 square + 5 square = 144 + 25 = 169

AC square = 13 * 13 = 169

AC = 13 km

Distance starting and ending point  = AC = 13 km
