I’m not sure if this is what you’re looking for, but since there’s a time limit i’m going to share what i came up with.
for every 4 miles, 1 bottle of water is needed. this can be represented by the ratio 4:1
so for another 4 miles, he will need 2 bottles of water, which is shown in the ratio 8:2
going along with this pattern of adding 4 miles it will be continued with
12:3
16:4
20:5
24:6
28:7
32:8
