According to the question, Jacob jogged 3 miles in 30 minutes on Wednesday and 5 miles in 50 minutes on Thursday
the proportional relationship between the number of miles jogged and the time spent jogging:-
so, the ratio of Wednesday and Thursday jogging of Jacob => 3/30 = 5/50
1/10 = 1/10
so the ratio of wednesday and thrusday is same 1:10
now Otto jogged 4 miles in 32 minutes on Wednesday and 6 miles in 50 minutes on Thursday
so, ratio of Wednesday and Thursday jogging of Otto => 4/32 = 6/50
1/8 = 2/25
here ratio of Otto is not correct !
