Sam lives 3.5 times farther from school than Sara does. Sam lives 13.3 miles from school. How far from school does Sara live?

Sara lives 3.8 miles away from the school

Explanation:

Sam lives 3.5 times farther than Sara

Sam lives 13.3 miles away from school

Opposite of multiplication is division, so we must divide to see how far away Sara lives from the school

13.3 : 3.5 = 3.8

Sara lives 3.8 miles away from the school

Let distance of Sarah from school = x

Distance of sam from school = 3.5x or 13.3

=> 3.5x = 13.3

X = 13.3 / 3.5

X = 3.8
