Human: It took Dad 5 more than twice as long to vacuum upstairs then to vacuum downstairs. He vacuumed for a total of 38 minutes. How many minutes did he vacuum upstairs? Assistant:
Let D = time in minutes to vacuum downstairs
Upstairs = 2D + 5 minutes
3D + 5 = 38
3D = 33
D = 11 minutes
Upstairs = (2 * 11) + 5 = 27 minutes
Dad took 27 minutes to vacuum upstairs.
