Rubi goes to a multiplex at the speed of 3 km/hr to see

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

Distance between starting
point and multiplex = x metre

Time =	Distance
	Speed

According to the question,

x	−	x	=	5 + 5	⇒	4x − 3x	=	1
3	−	4	=	60	⇒	12	=	6

⇒	x	=	1	⇒ x =	12	= 2 km.
	12		6		6
