A trolley charges $2.00 for every mile traveled. How much would it cost to travel 5 miles? 8 miles? 20 miles?

Question

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.
