If taxi fares were $1.00 for the first 1/5 mile and$0.20 for each 1/5 mile there after, then the taxi fare for a 3-mile ride was

a) $1.56 b)$2.40
c) $3.80 d)$4.20
e) $2.80 [Reveal] Spoiler: My Doubt 1dollar=1/5mile, so 5 dollars = 1 mile then, 1/5 dollar=1/5 mile, so 1 dollar = 1mile so 3miles/7dollars, approximately equal to$4.20

where am I wrong???

I wonder why did you write "3miles/7dollars" in your solution.

Anyway, the question says:

The taxi charges $1 for the FIRST $$\frac{1}{5}miles$$. And any additional $$\frac{1}{5}mile$$ is charged at a rate of$0.20.

How many $$\frac{1}{5} miles$$ are there in 3 miles? 15, right?

1 mile has five $$\frac{1}{5} miles$$ parts.
3 miles have fifteen $$\frac{1}{5} miles$$ parts.

The first part is charged @ $1.00 per part. Rest 14 parts are charged @$0.20 per part.

Total Fare=1*$1.00+14*$0.2=$1.00+$2.8=$3.8 Ans: "C" _________________ Director Joined: 01 Feb 2011 Posts: 757 Followers: 14 Kudos [?]: 108 [0], given: 42 Re: If taxi fares were$1.00 for the first 1/5 mile and $0.20 for each 1/5 [#permalink] ### Show Tags 13 Aug 2011, 15:32 In 3 miles , initial 1/5 mile charge is$1
rest of the distance = 3 - (1/5) = 14/5
rest of the distance charge = 14(0.2) = $2.8 (as the charge is 0.2 for every 1/5 mile) => total charge for 3 miles = 1+2.8 = 3.8 Answer is C.

c) $3.80 d)$4.20
e) $2.80 3 Miles can be divided in 3/(1/5) = 15 equal part... Charges for First mile part =$ $$1.00$$ ,

Distance left = 14 parts

Charges for the next 14 parts = 0.20 * 14 => $2.8 Total charges = 1.00 + 2.8 =>$ 3.80

Hence, Correct answer will be (C)
