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.
