Question

A person strats from office travels a distance of 17 km southwards then travel a distance of 10 km towards east then a distance of 12 km towards west to rach his house how far his office from his house

Answer 1

39 km is the answer.

Answer 2

Answer:

Distance between house and office = 17.11 km.

Step-by-step explanation:

By using Pythagoras theorem, we get

a²+b²=c²

so by applying this formula, we get, for a right angled triangle,

17²+2² = (distance between home and office)²

so distance = √(17²+2²) = √(293) = 17.11 km.

since the eastward 10 km and westward 12 km will cancel out each other and remaining 2 km is taken into account.
