72 miles Sophie bike last week. we get the answer by making and solving equation.
Let's take x miles, Sophie swam
from the question we get,
she runs ⇒3 × x = 3x miles
she biked ⇒ 3 × 3x = 9x miles
Then by solving, ⇒3x + 9x + x = 104
⇒ 13x = 104
⇒ x = 8
therefore, we get
9x = 9 × 8
= 72 miles
lastly, we get that she biked 72 miles last week.
