Question

On a map of Pacific Northwest, the scale is such that 1 inch equals 6 miles. Using the map, the distance from Seattle to San Francisco is 133 1/3 inches. How far is the round trip from Seattle to San Francisco in miles, rounded to the nearest mile ?

Answer 1

Answer:

1600 miles

Step-by-step explanation:

Given:

The scale of the map is given as:

1 inch = 6 miles

Now, on the map, the distance between Seattle and San Francisco is $133\frac{1}{3}$ inches.

The actual distance is obtained by multiplying the map distance with the scale value. So, the actual distance from Seattle to San Francisco in miles is given as:

$\textrm{Actual distance}=133\frac{1}{3}\times 6=133.33\times 6=799.98\ mi$

Now, for round trip, we need to add the same distance again. So, total distance in round trip is given as:

799.98 + 799.98 = 1599.96 miles ≈ 1600 miles (Rounded to nearest mile)
