Worked practice questions

A man covers a distance in 6 hours at 40 km per hour. To cover it in 4 hours he must travel at:

50 km per hour
55 km per hour
65 km per hour
60 km per hour

Show answer and solution

Correct answer: D. 60 km per hour

1. First find the distance: 40 x 6 = 240 km. 2. The distance does not change, so speed and time are in inverse proportion. 3. The required speed is 240 / 4. 4. That is 60 km per hour. 5. Checking the ratio, the time fell to two thirds, so the speed must rise to three halves: 40 x 3 / 2 = 60. _Source: syllabus Maths, Ch 11 'Direct and Inverse Proportions', S11.3 Inverse Proportion_

A car uses 4 litres of petrol for 60 km. Its mileage in km per litre is:

Show answer and solution

Correct answer: C. 15

1. Mileage is distance divided by fuel used. 2. Here that is 60 km for 4 litres. 3. So the mileage is 60 / 4. 4. That is 15 km per litre. 5. This constant ratio is what makes distance and petrol directly proportional: 12 litres would carry the car 180 km. _Source: syllabus Maths, Ch 11 'Direct and Inverse Proportions', S11.2 Direct Proportion_
