Let the distance between Andheri and Bandra be

*x* km and the distance between Bandra and Dadar be

*y* km.

∴ 2(

*x* +

*y*) + 60 = 4

*x* + 10

∴ 2

*x* − 2

*y* = 50

∴

*x* −

*y* = 25,

Now ratio of speed of Arjun and Bharat is,

Ratio of distance travel by Arjun and Bharat is same as ratio of speed of Arjun and Bharat.

∴

*x* = 4

*y*

∴ 4

*y* ‒

*y* = 25

*y* = 8.33 km

Hence, option 4.
