QUESTION 4
4.1
An American family, Mr. and Mrs. Jones is visiting friends in Johannesburg. Whilst in Johannesburg they get information about the wild coast and decide to book a holiday at Kei mouth in the Eastern Cape Province. At Kei mouth you can take a ferry through the Kei River to Qolora for fishing which is 10 km from the Kei mouth.
This service does not operate when the river is in flood.
|
4.1.1 They arrived at the airport at 08:00 and they spend 3 hours and 45 minutes in East London. They travelled to Kei mouth at an average speed of 90 kilometers per hour.
Show by using calculations whether they will arrive on time to have lunch at 12:30 at Kei Mouth.
You may use the formula: Average speed = distance travelled
time taken (6)
4.1.2 If they hire a car from Avis and decide to go for fishing in Qolora for two days, they will need to use the ferry to and from Qolora during those two days. They feel that 700 American dollars will be enough to cover the hiring, accommodation and ferry rides. Use calculations to support this statement if the exchange rate during their vacation is 1 American dollar ($) = 14,391 South African rand. (6)
4.1.3 There is a warning that when the river is in flood, there will be no ferry rides. What is the reason for this? (2)
