NSC Mathematical Literacy Using predictions in various situations: During February 2017 tropical st

Question

During February 2017 tropical storm Dineo caused damage to property in Mozambique, but it also brought much needed rain. Below is a chart issued by Meteo France (the French weather office) showing the projected path of the storm as well as likely affected land areas.

Data on 14/02/2017 at 10h from Reunion

- the centre (also called the eye) of the storm
- Predicted path of the storm
- Possible affected land areas

NOTE: 15/10h indicates the predicted position at 10:00 on 15 February.

Dineo was classified as a Category 1 tropical storm with a maximum average wind speed of 95 miles per hour.

NOTE: 50 miles = 80,467 km

Convert (rounded off to TWO decimal places) the maximum average wind speed to kilometres per hour.

The distance between two vertical gridlines on the map is approximately 205,043 km.

Calculate, using the measured distance, the predicted average speed (in km/h) of the storm from point P to point Q.

You may use the following formula:

Distance = average speed x time
