Final answer:

The trip from Las Vegas took approximately 3913.14 miles.

Step-by-step explanation:

To find the time it took for the trip from Las Vegas, we can use the formula: Speed = Distance / Time. Let's denote this as:

Speed₁ = 161 mph

Speed₂ = 230 mph

Time₂ = 7 hours

We know that the distance going and returning is the same, so let's denote the distance as 'D':

Distance = D

Using the formula, we can write two equations:

Speed₁ = D / Time₁

Speed₂ = D / Time₂

Substituting the given values, we have:

161 = D / Time₁

230 = D / 7;

To solve for 'D', we can rearrange the second equation to find 'D', and then substitute into the first equation:

230 * Time₁ = 7 * D;

Time₁ = 7 * D / 230;

Substituting the value of Time₁ into the first equation:

161 = (7 * D / 230) / Time₁

Simplifying, we get:

161 * Time₁ = 7 * D / 230;

161 * Time₁ = 7D / 230;

161 * Time₁ = 7D / 230;

Cross multiplying:

161 * 230 = 7D * Time₁;

Simplifying, we get:

D = 161 * 230 / (7 * Time₁);

Substituting the given value of Time₂ into the equation:

D = 161 * 230 / (7 * 7);

Calculating, we get:

D = 3913.14;

Thus, the trip from Las Vegas took approximately 3913.14 miles.
