2.1.1 Determine if vehicles travelling from Malmesbury to N in block I8 on the topographic map, will drive uphill or downhill. (1 x 1) (1)
2.1.2 Give a reason for your answer to QUESTION 2.1.1. (1 x 1) (1)
2.1.3 Calculate the distance, in km, from N in block I8 on the topographic map to Cape Town. Show ALL calculations. Marks will be awarded for calculations. Clearly indicate the unit of measurement in your final answer.
Formula: ActualDistance = Map Distance x Scale (4 x 1) (4)
2.2 Refer to line O-P that connects contour line 120 at O and spot height 162 at P in blocks I9 and I11 on the topographical map.
2.2.1 Draw a freehand cross-profile from O to P.
2.2.2 Give ONE reason why there is no intervisibility between O and P (1 x 1) (1)
2.2.3 If you use a vertical scale of 1 cm represents 25 m to draw the cross-profile, determine the vertical exaggeration of the cross profile. Show ALL calculations. Marks will be awarded for calculations. Clearly indicate the unit of measurement in your answer. (4 x 1) (4)
Formula: Vertical exaggeration = vertical scale
horizontal scale
