AlgebraMediumFare from a rate per fixed distance
Algebra practice question
A taxi meter starts at $3.20 and adds $0.40 for every 200 metres travelled. What is the fare, in dollars, for a journey of 3 kilometres?
Answer: 9.2
3 km = 3,000 m = 15 units of 200 m. Fare = 3.20 + 0.40(15) = 9.20.
Common wrong answers
- If you answered 6
- 6 is the distance charge alone, without the $3.20.
- If you answered 4.4
- 4.40 adds 0.40 per kilometre instead of per 200 metres.
- If you answered 1203.2
- 1,203.20 adds 0.40 per metre.
