Data set 5: Distances from New Zealand by sea
Data set 5
1. Answer A, 2,400 Nmiles
Explanation: The distance from New Zealand to Brisbane (1,200 Nmiles) can be read from the bar chart and the distance there and back is therefore 2,400 Nmiles.
2. Answer C, 2,450
Explanation: Simply total the number of passages for each month from April (300) to December (100).
3. Answer D, 1,540 miles
Explanation: In the notes we are told that an Nmile is 10% greater than a land mile so the distance from New Zealand to Tonga measured in land miles in 110% of the distance in Nmiles.
1,400 × 110% = 1,540 miles.
4. Answer B, 150,000 Nmiles
Explanation: In December there are 100 passages and 50 travel 1,000 Nmiles to Sydney, the other 50 travel 2,000 Nmiles to Fiji; this gives (50 × 1, 000 = 50,000) + (50 × 2,000 = 100,000) =
150,000 Nmiles in total.
5. Answer D, Cannot tell
Explanation: We are not given enough information regarding their relative positions and so there is insufficient information to calculate the distance between Sydney to Fiji.
6. Answer C, 1 : 5
Explanation: There are 5 stormy days and 25 non-stormy days during the period. This gives the ratio 5 : 25, which expressed in its simplest form is 1 : 5.
7. Answer A, , Half
Explanation: From a previous question the total number of passages was calculated to be 2,450. The total for the months June–September is 1,200 which is slightly less than half the total for the year.
8. Answer B, Both passages would take the same amount of time
Explanation: The passages are the same distance and both would experience adverse currents one way and favourable currents the other, so the effect of the currents is cancelled out. Therefore you would expect the passages to take the same amount of time.
9. Answer D, 294
Explanation: There were a total of 2,450 sailings. To find 12% of this total, divide by 100 to get 1% and then multiple by 12 (2450 ÷ 100 = 14.5 × 12 = 294).
10. Answer A, 125 hours
Explanation: The distance is 1,000 Nmiles and the speed that counts is the speed over the ground (the speed through the water will be higher because of the counter current)
The answer is therefore 1,000 ÷ 8 = 125.
