1.1. This map shows part of a village.

Neil knows that Packer Street is 180m long in real life.

i) Neil measures the map.
He says

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

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

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

ii) Jodie measures the same map.

She says

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

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

1.2. On another map, Packer Street is 2.4cm long.

Express the scale of this map in the form 1 : $n$.
