Answer:

Miles, Lucinda skied on Saturday = 42

Miles, Lucinda skied on Sunday = 21

Step-by-step explanation:

Given:

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

Total miles skied over the weekend = 63

To find the miles she skied each day.

Solution:

<em>Let the miles Lucinda skied on Sunday be</em> = x

On Saturday, she skied twice as many mile as on Sunday.

<em>Thus, miles Lucinda skied on Saturday will be</em> = 2x

The total miles skied over the weekend will be given as:

⇒ x+2x

⇒ 3x

Thus we can equate the above expression with the total miles skied over the weekend.

We have:

3x=63

Solving for x

Dividing both sides by 3.

\frac{3x}{3}=\frac{63}{3}

∴ x=21

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