Step-by-step explanation:
Lets first find the feet they walk per day, multiply the steps by the feet/step:

Now lets find the feet/week by multiplying that value by 7:

Now lets convert the feet to km:

Resulting in approximately 55 kilometers

15+(0.25x)
15+(0.25×80)
15+(20)
35

20+(0.05x)
20+(0.05×300)
20+(15)
35
I am sure there are other numbers that you can use but I just choose the number 35! Good luck!
