QUESTION 1
1.1 The Western Cape is the fourth largest of the nine provinces of South Africa. It has
an land area of 49 983,56 square miles and a population of 5,8 million people.
About two-thirds of the people in the Western Cape live in Cape Town and the
surrounding areas. The rest live in rural parts of the province.
The map of the province is shown below. Use the map and the given information to
answer the following questions.
1.1.1 Write down the name of the MOST eastern town shown on the map. (2)
1.1.2 Use a ruler to measure the direct map distance (as the crow flies) from
Hermanus to Oudtshoorn. Give your answer in millimeter.
(2)
1.1.3 Use the scale on the map to calculate the actual distance in kilometres
between Hermanus and Oudtshoorn.
(4)
1.1.4
Determine the ratio, in simplest form, of people living in Cape Town and
the surrounding areas to those living in rural areas.
(3)
1.1.5 Convert the land area of the Western Cape to the nearest km2 if
1 km = 0, 62139 miles.
(3)
1.1.6 Calculate the population density of the Western Cape in people/km2.

1.2 To transport people to the top of the table mountain TWO cable cars are used.
The following information can be used:
Each of the cable cars can carry 65 people.
Each cable car travels at a maximum speed
of 10 m/second.
It takes the cable car 5 minutes to reach the
top of the mountain.
A cable car goes to the top of the mountain
every 9 minutes.
The maximum weight of passengers a cable car
can carry is 5 200 kg.
1.2.1 You are 338th
in the line that awaits to go to the top of the mountain. At
what time will you reach the top if the first group in the line boards the
cable car at 08:27?
(6)
1.2.2 Calculate the distance in meters travelled by a cable car to transport
people to the top of the mountain.
The formula may be used : Average speed = time
distance
(4)
1.2.3 Calculate the maximum average (mean) weight in kg of the passengers if
the maximum number of passengers is transported in the cable car.
(3)
1.3 Use the following rates for the cable car to answer the question that follows:
Rates for Cable Car: Rates (in South African Rand) are valid from 1 October 2014 to 30 September 2015:
Ticket Type Return One way
Adult 225 115
Child 4 -17 years 110 58
SA senior citizen (Fridays only at ticket office) 95 50
Students (Fridays only at ticket office) 130 68
A family( father, mother, student son and two children, 16 years and 10 years) decide
to visit table mountain on a Friday. They decide to walk up to the top and come down
by cable car so that they can save money.
How much money do they save?

2.3 A cylindrical barrel (drum) contains 42 gallons of oil. The diameter of this barrel is
18 inches.
You may use the following information:
1 gallon = 3,78541 litres
1 inch = 2,54 cm
1 ml = 1 cm3
Volume = π × r2 × h, let π = 3,142
Area of a circle = π × r2
Surface area of cylinder with a closed lid and base = (2 × π × r2) + (2 × π × r × h)
2.3.1 Determine the radius of a barrel (drum) in centimetres. (3)
2.3.2 Show, by calculations, that the height of the barrel of oil is 96,82 cm. (5)
2.3.3 Calculate the surface area of this barrel in m2. (5)
