Answer:_______________

Answer: 24 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	84 $\frac{km}{h}$ x $\frac{1}{3}$ h
		=	28 km

Step 2:	Time needed by Nandini	→	28 km ÷ 70 $\frac{km}{h}$
		=	0.4 h
		=	0.4 x 60 min
		=	24 min

Answer: 24 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	96 $\frac{km}{h}$ x $\frac{1}{3}$ h
		=	32 km

Step 2:	Time needed by Pavi	→	32 km ÷ 80 $\frac{km}{h}$
		=	0.4 h
		=	0.4 x 60 min
		=	24 min

Answer: 12 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	42 $\frac{km}{h}$ x $\frac{1}{3}$ h
		=	14 km

Step 2:	Time needed by Selvanayaki	→	14 km ÷ 70 $\frac{km}{h}$
		=	0.2 h
		=	0.2 x 60 min
		=	12 min

Answer: 18 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	63 $\frac{km}{h}$ x $\frac{1}{3}$ h
		=	21 km

Step 2:	Time needed by Indra	→	21 km ÷ 70 $\frac{km}{h}$
		=	0.3 h
		=	0.3 x 60 min
		=	18 min

Answer: 12 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	36 $\frac{km}{h}$ x $\frac{1}{3}$ h
		=	12 km

Step 2:	Time needed by Indra	→	12 km ÷ 60 $\frac{km}{h}$
		=	0.2 h
		=	0.2 x 60 min
		=	12 min

Answer: 24 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	72 $\frac{km}{h}$ x $\frac{1}{3}$ h

		=	0.4 h
		=	0.4 x 60 min
		=	24 min

Answer: 24 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	72 $\frac{km}{h}$ x $\frac{1}{3}$ h
		=	24 km

Step 2:	Time needed by Chellamal	→	24 km ÷ 60 $\frac{km}{h}$
		=	0.4 h
		=	0.4 x 60 min
		=	24 min

Answer: 12 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	36 $\frac{km}{h}$ x $\frac{1}{3}$ h

Answer: 12 min

SOLUTION 1 :

Step 1:	Distance from the cinema to the shopping mall	→	48 $\frac{km}{h}$ x $\frac{1}{3}$ h
		=	16 km

Step 2:	Time needed by Chithra	→	16 km ÷ 80 $\frac{km}{h}$
		=	0.2 h
		=	0.2 x 60 min
		=	12 min
