Answer:
Eliza travels 54 minutes.
Explanation:
Let's use the variable r to represent the number of minutes Ricky travles to school.
Eliza travels 6 times as many minutes as Ricky, so Eliza travels 6r minutes.
Altogether, they travel r + 6r minutes, or 7r minutes.
We are told they travel 63 minutes altogether, so 7r must equal 63.
7r = 63
Divide both sides by 7.
7r/7 = 63/7
r = 9
Ricky travels 9 minutes.
Eliza travels 6r minutes.
6r = 6 * 9 minutes = 54 minutes
Eliza travels 54 minutes.
