Question

A trolley charges $2.00 for every mile traveled. How much would it cost to travel 5 miles? 8 miles? 20 miles?
What is the cost per mile for each of the distances traveled?
Number of miles (m) Cost in dollars (c) Cost per mile (

c
​
)
5 $10.00
8 $16.00
20 $40.00

Answer 1

To calculate the cost of traveling different distances in a trolley that charges $2.00 per mile, we can use the formula:

\[
\text{Cost} = \text{Distance} \times \text{Cost per mile}
\]

Here, the cost per mile is $2.00.

Now, let’s calculate the costs for each distance:

1. **For 5 miles:**
\[
\text{Cost} = 5 \, \text{miles} \times 2.00 \, \text{dollars/mile} = 10.00 \, \text{dollars}
\]

2. **For 8 miles:**
\[
\text{Cost} = 8 \, \text{miles} \times 2.00 \, \text{dollars/mile} = 16.00 \, \text{dollars}
\]

3. **For 20 miles:**
\[
\text{Cost} = 20 \, \text{miles} \times 2.00 \, \text{dollars/mile} = 40.00 \, \text{dollars}
\]

Now, let's summarize the costs and compute the cost per mile for each distance traveled:

| Number of miles (m) | Cost in dollars (c) | Cost per mile (c/m) |
|----------------------|----------------------|----------------------|
| 5 | $10.00 | $2.00 |
| 8 | $16.00 | $2.00 |
| 20 | $40.00 | $2.00 |

### Summary:
- **Cost to travel 5 miles:** $10.00
- **Cost to travel 8 miles:** $16.00
- **Cost to travel 20 miles:** $40.00

In all cases, the cost per mile is consistently $2.00.
