6. In what direction is the river flowing? [1 mark]

Use the following diagram to answer the following questions.

7. What is the length of the road, in kilometres, between X and Y? [2 marks]

8. Calculate the gradient of Slope A-B and CD. (Show full working.) [8 marks]

Tips for answering questions

With grid references, the rate of error is +/- 1. (except when the point is on a major

Easting and Northing line, where answer will be 0).

Remember to state formulas before any calculations, e.g. gradient.

Show ALL working for calculations.

Be careful when converting from one unit to the next (e.g. km to m, etc.).

Cross sections MUST have a title, labelled axes and a scale for the vertical axis.

Cross sections must include any major features, like roads and rivers, etc.

Be neat!
