Here are the distances (as the crow flies) in km from London to various cities in the world:
Abu Dhabi 5480 Barcelona 1139 Cape Town 9680
Delhi 6718 Edmonton 6805 Florence 1209
Gothenburg 1039 Houston 7812 Istanbul 2501
Jerusalem 3611 Karachi 6314 Lauceston 17425
If someone took you the first 1000km how much further would you have to go for each of the twelve journeys?
Rather than actually performing each calculation, could you say which you think will be the most difficult and which will be the easiest, and why?
Now create some similar questions of your own.
If you started at Copenhagen then went to London, which is about 1000 km away each time for all of the journeys shown above, how far would you have travelled in each case?
