Higher November 2018 Paper 6 Q5

(a) Neil measures the map.

He says

Packer Street is 3.5 cm long.
High Street is 11.2 cm long.

Therefore, I calculate that High Street is 576 m long in real life.

Use Neil’s figures to show that the answer to his calculation is correct. [3]

(b) Jodie measures the same map.

She says

I think Packer Street is longer than Neil’s measurement of 3.5 cm.
Therefore, High Street must be longer than 576 m in real life.

Is Jodie’s reasoning correct?
Show how you decide. [2]

(c) On another map, Packer Street is 2.4 cm long.

Express the scale of this map in the form 1 : n. [2]
