Question

Luis walked for 16 minutes. Natalie walked for w minutes. Luis walked twice as long as Natalie. How long did Natalie walk ?Write an equation and solve.

Answer 1

Since Natalie walked for w minutes

Since Luis walked twice as long as Natalie, then

Luis walked = 2 x w = 2w minutes

Since Luis walked for 16 minutes, then equate 2w by 16

The equation is

`2w=16`

To solve it divide both sides by 2

`\begin{gathered} (2w)/(2)=(16)/(2) \\ w=8 \end{gathered}`

The solution is 8

Natalie walked for 8 minutes
