Question

You use 1/8 of your battery for every 2/5 of an hour that you video chat you use 3/4 of your battery. How long did you video chat

Answer 1

To find the duration of the video chat, we set up a proportion using the amount of battery used and the duration of the chat. Solving the proportion, we find that the duration is 1.2 hours.

Step-by-step explanation:

To solve this problem, we can set up a proportion between the amount of battery used and the duration of the video chat.

Let's call the duration of the video chat 'x' in hours. Using the information given, we have the following proportion:

1/8 battery used : 2/5 hour of video chat = 3/4 battery used : x hour of video chat

Now, we can cross-multiply and solve for 'x':

1/8 * x = (2/5) * (3/4)

Dividing both sides by 1/8, we get:

x = (2/5) * (3/4) / (1/8)

x = (2/5) * (3/4) * (8/1)

x = 6 / 5

Therefore, the duration of the video chat is 6/5 or 1.2 hours.
