Users of the video app Webbed Flicks are required to watch 15-second ads before they can watch their video. Grace watched ads for 60 seconds before her video started.

Question

Let x represent how many ads Grace had to watch. Which equation models the problem?
15x=60
x
15
=60
Solve this equation to find how many ads Grace had to watch.
ads

Answer 1

To model the problem, we can represent the duration of each ad and the total time Grace spent watching ads with the equation:

\[ 15x = 60 \]

where:

• \( x \) represents the number of ads Grace had to watch, and
• \( 15 \) is the duration of each ad in seconds.

Now, we can solve the equation for \( x \):

1. Start with the equation: \[ 15x = 60 \]

2. To isolate \( x \), divide both sides of the equation by 15: \[ x = \frac{60}{15} \]

3. Simplifying the right side: \[ x = 4 \]

Therefore, Grace had to watch 4 ads before her video started.
