Question

Aaron receives 20 minutes of video game time every 45 minutes of dog walking he does. If he wants 90 minutes of game time, how many hours will he need to work

Answer 1

Answer:3.375 or 3.38 hours

Explanation:

20 minutes of game time / 45 minutes of dog walking = 90 minutes of game time / x

Cross-multiplying gives:

20 * x = 45 * 90

Now, solve for "x":

x = (45 * 90) / 20

x = 202.5

This means Aaron needs to work for 202.5 minutes to earn 90 minutes of game time.

To convert minutes to hours:

1 hour = 60 minutes

So, Aaron needs to work:

202.5 minutes / 60 = 3.375 hours

Rounded to two decimal places, Aaron needs to work approximately 3.38 hours to earn 90 minutes of game time.
