Worked Solution & Example Answer:During February 2017 tropical storm Dineo caused damage to property in Mozambique, but it also brought much needed rain - NSC Mathematical Literacy - Question 4 - 2017 - Paper 2
Step 1
Convert (rounded off to TWO decimal places) the maximum average wind speed to kilometers per hour.
Answer
The maximum average wind speed of Dineo is 95 miles per hour. To convert this speed to kilometers per hour, we use the conversion factor:
Thus,
= 152.887 ext{ km/h}$$ Rounding off to two decimal places, the maximum average wind speed is: **152.89 km/h**.Step 2
Calculate, using the measured distance, the predicted average speed (in km/h) of the storm from point P to point Q.
Answer
Using the formula:
From the question, the distance between points P and Q is approximately 205,043 km. We can assume a time duration for the storm's movement between these points. Let’s suppose it takes 24 hours:
Using the values:
= 8,544.29 ext{ km/h}$$ Thus, the average speed of the storm from point P to point Q is approximately: **8,544.29 km/h**.
