Answer:_______________

Answer: 7.15 p.m.

SOLUTION 1 :

Step 1:	Time after the motorist finished the first $\frac{1}{4}$ of the journey	→	1.40 p.m. + 20 min
		=	2.00 p.m.

Step 2:	Time used to travel the last $\frac{3}{4}$ of the journey	→	210 km ÷ 40 $\frac{km}{h}$
		=	5.25 h
		=	5 h 15 min

Step 3:	Time when the motorist finished the journey	→	2.00 p.m. + 5 h 15 min
		=	7.15 p.m.

Answer: 4.15 p.m.

SOLUTION 1 :

Step 1:	Time after the motorist finished the first $\frac{1}{4}$ of the journey	→	1.40 p.m. + 20 min
		=	2.00 p.m.

Step 2:	Time used to travel the last $\frac{3}{4}$ of the journey	→	90 km ÷ 40 $\frac{km}{h}$
		=	2.25 h
		=	2 h 15 min

Step 3:	Time when the motorist finished the journey	→	2.00 p.m. + 2 h 15 min
		=	4.15 p.m.

Answer: 6.45 p.m.

SOLUTION 1 :

Step 1:	Time after the motorist finished the first $\frac{1}{4}$ of the journey	→	1.40 p.m. + 20 min
		=	2.00 p.m.

Step 2:	Time used to travel the last $\frac{3}{4}$ of the journey	→	190 km ÷ 40 $\frac{km}{h}$
		=	4.75 h
		=	4 h 45 min

Step 3:	Time when the motorist finished the journey	→	2.00 p.m. + 4 h 45 min
		=	6.45 p.m.

Answer: 4.00 p.m.

SOLUTION 1 :

Step 1:	Time after the motorist finished the first $\frac{1}{4}$ of the journey	→	1.40 p.m. + 20 min
		=	2.00 p.m.

Step 2:	Time used to travel the last $\frac{3}{4}$ of the journey	→	80 km ÷ 40 $\frac{km}{h}$
		=	2 h
		=	2 h 0 min

Step 3:	Time when the motorist finished the journey	→	2.00 p.m. + 2 h 0 min
		=	4.00 p.m.

Answer: 5.15 p.m.

SOLUTION 1 :

Step 1:	Time after the motorist finished the first $\frac{1}{4}$ of the journey	→	1.40 p.m. + 20 min

Answer: 3.45 p.m.

SOLUTION 1 :

Step 1:	Time after the motorist finished the first $\frac{1}{4}$ of the journey	→	1.40 p.m. + 20 min
		=	2.00 p.m.

Step 2:	Time used to travel the last $\frac{3}{4}$ of the journey	→	70 km ÷ 40 $\frac{km}{h}$
		=	1.75 h
		=	1 h 45 min

Step 3:	Time when the motorist finished the journey	→	2.00 p.m. + 1 h 45 min
		=	3.45 p.m.
