You finished a fourth of your homework in 60 minutes. How many hours did it take you to finish all of it?
If you finished a fourth of your homework in 60 minutes, then you completed the remaining three-fourths in 60 minutes * 3 = <<60*3=180>>180 minutes.
Since there are 60 minutes in an hour, it took you 180 minutes / 60 minutes per hour = <<180/60=3>>3 hours to finish all of your homework. Answer: \boxed{3}.
You finished a fourth of your homework in 45 minutes. How many hours did it take you to finish all of it?
If you finished a fourth of your homework in 45 minutes, then you completed the remaining three-fourths in 45 minutes * 3 = <<45*3=135>>135 minutes.
Since there are 60 minutes in an hour, it took you 135 minutes / 60 minutes per hour = <<135/60=2.25>>2.25 hours to finish all of your homework. Answer: \boxed{2.25}.
You finished a fourth of your homework in 15 minutes. How many hours did it take you to finish all of it?
If you finished a fourth of your homework in 15 minutes, then you completed the remaining three-fourths in 15 minutes * 3 = <<15*3=45>>45 minutes.
Since there are 60 minutes in an hour, it took you 45 minutes / 60 minutes per hour = <<45/60=0.75>>0.75 hours to finish all of your homework. Answer: \boxed{0.75}.
You went to the doctor. There are 10 patients waiting ahead of you. The nurse told you it will be your turn after 4 hours. How many minutes would the doctor use to see each patient?
If there are 10 patients ahead of you and it takes 4 hours for your turn to come, then the total waiting time for those 10 patients is 10 * 4 = <<10*4=40>>40 hours.
Since an hour has 60 minutes, the waiting time in minutes is 40 * 60 = <<40*60=2400>>2400 minutes.
Therefore, the doctor would spend 2400 minutes / 10 patients = <<2400/10=240>>240 minutes to see each patient. Answer: \boxed{240}.
You went to the doctor. There are 10 patients waiting ahead of you. The nurse told you it will be your turn after 3 hours. How many minutes would the doctor use to see each patient?
If there are 10 patients ahead of you and it takes 3 hours for your turn to come, then the total waiting time for those 10 patients is 10 * 3 = <<10*3=30>>30 hours.
Since an hour has 60 minutes, the waiting time in minutes is 30 * 60 = <<30*60=1800>>1800 minutes.
Therefore, the doctor would spend 1800 minutes / 10 patients = <<1800/10=180>>180 minutes to see each patient. Answer: \boxed{180}.
To find out how many hours it took to finish all of the homework, we need to calculate the time taken for one fourth of the homework and then multiply it by four since there are four parts in total.
First, we find the time taken for one fourth of the homework. We know that it takes 60 minutes to finish one fourth, so we divide 60 by 1/4:
60 minutes ÷ 1/4 = 60 minutes × 4/1 = 240 minutes
Now, we have the total time in minutes. To convert it to hours, we divide by 60 since there are 60 minutes in an hour:
240 minutes ÷ 60 = 4 hours
Therefore, it took 4 hours to finish all of the homework.
