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:
Let the miles Lucinda skied on Sunday be = [tex]x[/tex]
On Saturday, she skied twice as many mile as on Sunday.
Thus, miles Lucinda skied on Saturday will be = [tex]2x[/tex]
The total miles skied over the weekend will be given as:
⇒ [tex]x+2x[/tex]
⇒ [tex]3x[/tex]
Thus we can equate the above expression with the total miles skied over the weekend.
We have:
[tex]3x=63[/tex]
Solving for [tex]x[/tex]
Dividing both sides by 3.
[tex]\frac{3x}{3}=\frac{63}{3}[/tex]
∴ [tex]x=21[/tex]
Thus, Lucinda skied 21 miles on Sunday and twice that which is 42 on Saturday.
