Question

Can you pls help me with number 1 and 2 question thank you

Answer 1

8 minutes

Explanation:

The time Luis spent walking = 16 minutes

The time Natalie spent walking = w minutes

Luis walked twice as long as Natalie.

Twice means 2 times of something.

This means that we multiply Natalie's time by 2 to get Luis' time.

`\begin{gathered} Luis\text{ Time=}2\text{ }*\text{ Natalie's time} \\ \implies16=2w \end{gathered}`

Next, the equation is solved to see how long Natalie walked.

`\begin{gathered} 16=2w \\ \text{Divide both sides of the equation by 2} \\ (16)/(2)=(2w)/(2) \\ 8=w \\ \implies w=8\text{ minutes} \end{gathered}`

The time Natalie spent walking is 8 minutes.
