Step-by-step explanation:

To find the percentage of the total distance traveled by train, we can use the following formula:

Percentage = (Distance traveled by train / Total distance traveled) * 100

First, let's calculate the total distance traveled:

Total distance = 37 miles (by bus) + 75 miles (by train) + 13 miles (by car) = 125 miles

Now, we can find the percentage of the total distance traveled by train:

Percentage = (75 miles / 125 miles) * 100

Percentage = (0.6) * 100

Percentage = 60%

So, Anna traveled 60% of the total distance by train.

Answer:

60%

Step-by-step explanation:

To find the percentage of the total distance traveled by train, we first need to calculate the total distance traveled by Anna. Then, we can find the percentage of the distance traveled by train.

Total distance traveled by Anna:

[tex] \textsf{Total distance} = \textsf{Distance traveled by ( Bus + Train + Car } [/tex]

[tex] \textsf{Total distance} = 37 \textsf{ miles} + 75 \textsf{ miles} + 13 \textsf{ miles} [/tex]

[tex] \textsf{Total distance} = 125 \textsf{ miles} [/tex]

Now, we find the percentage of the distance traveled by train using the following formula:

[tex] \textsf{Percentage by train} = \left( \dfrac{\textsf{Distance by train}}{\textsf{Total distance}} \right) \times 100\% [/tex]

Substitute the value and simplify:

[tex] \textsf{Percentage by train} = \left( \dfrac{75}{125} \right) \times 100\% [/tex]

[tex] \textsf{Percentage by train} = \left( 0.6 \right) \times 100 \%[/tex]

[tex] \textsf{Percentage by train} = 60\% [/tex]

So, Anna traveled 60% of the total distance by train.
