PROBLEM

Track distances (miles) between railway stations are given below.
\begin{tabular}{lccccr} & Andertown & Housedon Nantbridge & Broxlake & Marlson \\ \hline Housedon & 45 & & & & \\ \hline Nantbridge & 164164^{*} & 37 & & & 56 \\ \hline Prexley & & 73 & 148148^{\star} & 61 & \\ \hline \end{tabular}
Tracks marked with an asterisk are main lines. All others are local lines.
Ticket prices are £1.10£ 1.10 per mile during peak travel and 47 p per mile for off-peak.
Train speeds are 86 mph on the main lines and 57 mph on the local lines.
What is the price per minute of a ticket when travelling off-peak from Nantbridge to Andertown?

STEP 1

What is this asking?
How much does it cost per minute to travel from Nantbridge to Andertown when it's not peak travel time?
Watch out!
We're dealing with different units: miles, pounds, pence, and minutes!
Don't mix them up!
Also, we only care about the off-peak price.

STEP 2

1. Calculate the off-peak ticket price.
2. Calculate the travel time.
3. Calculate the price per minute.

STEP 3

The distance from Nantbridge to Andertown is 164 miles.
The off-peak price is 47 pence per mile.
Let's convert the pence to pounds first.
There are 100 pence in a pound, so 47 pence is equal to 47÷100=47 \div 100 = $0.47\$0.47.

STEP 4

Now, we can multiply the distance by the price per mile to get the total ticket price in pounds.
164 miles$0.47/mile=$77.08164 \text{ miles} \cdot \$0.47/\text{mile} = \$77.08 So, the off-peak ticket price is $77.08.

STEP 5

The trip is on a main line, so the train speed is 86 mph.
We need to find out how long it takes to travel 164 miles at this speed.

STEP 6

Remember, speed is distance divided by time.
We can rearrange this formula to find the time: time is distance divided by speed.
Time=DistanceSpeed\text{Time} = \frac{\text{Distance}}{\text{Speed}}

STEP 7

Let's plug in our values:
Time=164 miles86 mph1.91 hours\text{Time} = \frac{164 \text{ miles}}{86 \text{ mph}} \approx 1.91 \text{ hours}

STEP 8

We need the time in minutes, not hours.
There are 60 minutes in an hour, so:
1.91 hours60minuteshour114.6 minutes1.91 \text{ hours} \cdot 60 \frac{\text{minutes}}{\text{hour}} \approx 114.6 \text{ minutes}

STEP 9

We know the total ticket price is $77.08, and the travel time is about 114.6 minutes.

STEP 10

To find the price per minute, we divide the total price by the total time:
$77.08114.6 minutes$0.67/minute\frac{\$77.08}{114.6 \text{ minutes}} \approx \$0.67/\text{minute}

SOLUTION

The price per minute for an off-peak ticket from Nantbridge to Andertown is approximately $0.67\$0.67.
