Lucinda skied 21 miles on Sunday and twice that is 42 on Saturday.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given:

On Saturday Lucinda skied twice as many miles as she did on Sunday.

The Total miles skied over the weekend = 63

Let the miles Lucinda skied on Sunday be = x

Thus, miles Lucinda skied on Saturday will be = 2x

The total miles skied over the weekend = x + 2x = 3x

We have:

3x = 63

Dividing both sides by 3.

x = 21

Hence, Lucinda skied 21 miles on Sunday and twice that is 42 on Saturday.
