What is the approximate number of cyclists and walkers in City C if 800 commuters were surveyed there?
A transport agency surveyed 2400 commuters in three cities. In City A, 38 per cent drive alone, 41 per cent use trains and 21 per cent cycle or walk. In City B, 62 per cent drive alone, 25 per cent use trains and 13 per cent cycle or walk. In City C, 29 per cent drive alone, 33 per cent use trains and 38 per cent cycle or walk. Average one-way trip times were 34 minutes in City A, 41 minutes in City B and 29 minutes in City C. City B has the lowest population density of the three; City C has the highest. Fuel prices were similar in all three cities. The agency's report states that dense cities 'produce' shorter commutes.
Answer and explanation
Correct answer: B. About 304
- Step 1: 38 per cent of 800 = 0.38 x 800 = 304. Answer: 304. Why not the others: 232 is 29 per cent, 264 is 33 per cent and 320 is 40 per cent.
