Interesting facts

The German Carl Benz built a motorcar with a petrol-driven engine in 1885. Its top speed was about 18 km per hour! Grandpa says that the first car to arrive in our country was imported in 1897. Cars were not built in factories on a large scale in South Africa at the time. Each one was built individually for some person who was wealthy enough to buy it. In time, however, less expensive cars like Grandpa's Model T Ford were built in factories.

Activity 2

To differentiate between different eras [lo 2.3]

A)talk about how transportation has developed since the early times that we have discussed!

Why would it be better if more people went to work by bus?

Why is the motorcar regarded as a convenient means of transport?

Nowadays, roads are more generally built of t . . r or of c . . . . . . . . . . e.

Good roads that are built to link large cities are known as n . . . . . . . . . . l roads.

B)going on a class outing!

Ask your educator to take you to a busy road or street where you can do a traffic count. You already know that transportation has changed over time. Now you have to find out whether there are noticeable changes that occur during a single day.

Take turns to work in pairs for an hour at a time.

Count the number of vehicles travelling past a certain point in both directions.

Give a report on the following when you are back in the classroom:

- At what time do most people travel to work and back?

- Such traffic is known as p . . . . . . . . . . k-hour traffic.

- Which kinds of vehicles are used most at different times? Explain this?

C)debate!

  • Which is used more during peak hours - motorbikes or minibuses?

Memorandum

a) 1. 5

  1. Own answers.
  2. The tracks were smoother and more level compared to the bad roads of that time.
  3. Let learners give own answers. The tram runs on steel rails – drawn by horses. (South Africa’s first tram came into operation between Cape Town and Green Point in 1863. Ladies were seated inside and men on top

Bicycles became popular in South Africa in the late 1800’s – without springs, tyres, and gears.

  1. In the 1600’s and 1700’s roads were ruts – also no bridges. People Walked, rode on horseback or travelled by ox-wagon. By 1820 the main-route was between Cape Town and Grahamstown after the arrival of the Settlers. Prisoners were often used to build roads. Read the story of Andrew Bain, South Africa’s best-known pioneer road-builder.
  2. Let learners provide own answers.
  3. After 1935 the surface of many gravel roads were covered with a layer of tar or cement. It was supposed to last for approximately 20 years.
  • Tar or bricks, national roads
  • Peak hour traffic

Wayne and Dennis like to ride the bike path from Riverside Park to the beach. Dennis’s speed is seven miles per hour faster than Wayne’s speed, so it takes Wayne 2 hours to ride to the beach while it takes Dennis 1.5 hours for the ride. Find the speed of both bikers.

from theory: distance [miles] = speed [mph] × time [hours] info #1 speed_Dennis × 1.5 = speed_Wayne × 2 => speed_Wayne = 0.75 × speed_Dennis (i) info #2 speed_Dennis = speed_Wayne + 7 [mph] (ii) use (i) in (ii) => [...] speed_Dennis = 28 mph speed_Wayne = 21 mph
George
Let W be Wayne's speed in miles per hour and D be Dennis's speed in miles per hour. We know that W + 7 = D and W * 2 = D * 1.5. Substituting the first equation into the second: W * 2 = (W + 7) * 1.5 W * 2 = W * 1.5 + 7 * 1.5 0.5 * W = 7 * 1.5 W = 7 * 3 or 21 W is 21 D = W + 7 D = 21 + 7 D = 28

Shakir works at a computer store. His weekly pay will be either a fixed amount, $925, or $500 plus 12% of his total sales. How much should his total sales be for his variable pay option to exceed the fixed amount of $925.
mahnoor Reply
I'm guessing, but it's somewhere around $4335.00 I think
Lewis
12% of sales will need to exceed 925 - 500, or 425 to exceed fixed amount option. What amount of sales does that equal? 425 ÷ (12÷100) = 3541.67. So the answer is sales greater than 3541.67. Check: Sales = 3542 Commission 12%=425.04 Pay = 500 + 425.04 = 925.04. 925.04 > 925.00
