Answer 1

Answer:

Correct option is

B

15 km

The movement of the person are as shown in fig.

Clearly AB = 3 km

BC=3AB=(3×3)KM=9KM

CD=5AB=(5×3)KM=15KM

Draw AE ⊥ CD.

Then CE = AB = 3 km and

AE = BC = 9Km

DE = (CD-CE)=(15-3)Km = 12 Km.

In Δ AED, AD

=AE

+DE

= AD=(

+(12)

)km=15km

∴ Required distance = AD = 15 Km.
