Rubi goes to a multiplex at the speed of 3 km/hr to see a movie and reaches 5 minutes late. If she travels at the speed of 4 km/hr she reaches 5 minutes early. Then the distance of the multiplex from her starting point is

2 km.
5 km.
2 metre
5 metre

Validate

Solution:

(1) Distance between starting point and multiplex = x metre
Time =

{ \Distance}/ {\Speed}

According to the question,

{ x }/ { 3 } - { x }/ { 4 } = { 5 + 5 } /{ 60 } ⇒ { 4 x - 3 x }/ { 12 } = { 1 }/ { 6 }

⇒{ x }/ { 12 } = { 1 }/ { 6 } ⇒ x = { 12 } /{ 6 } = 2 \ { \km }
