Question

Find the distance represented by 2.6 in. if the scale 1 in. = 50 mi. is used.

Answer 1

For the solution of this question we will use a technique called the Unitary Method. In this method we find the value of a single unit, which is 1, and then finding the necessary value by multiplying the single unit value.

In our case we are already given the value of the single unit which is 1 inch. And it is also given in the question that 1 inch = 50 miles. Thus, to find the value in miles 2.6 inches, all that we have to do multiply the single unit value, which is 50 miles, with the value given which is 2.6 inches.

Thus, we have:

If 1 inch represents 50 miles,

then 2.6 inches represents $2.6\times 50$ miles=130 miles

Thus, 130 miles is the correct answer.

Answer 2

The Answer would be 130 miles because if you have 2.6 in and 1 in = 50 miles just multiply 2.6 x 50 = 130.
