Hi Amy,

I analyzed the commute and physical activity survey data you sent to calculate the average daily time spent walking for males in the 20-30, 30-40, and 40-50 age groups. Here are the results:

Males age 20-30: 43.8 minutes per day
Males age 30-40: 35.2 minutes per day
Males age 40-50: 31.7 minutes per day

Let me know if you need anything else!

Best,
Deltaid
