Answer:
4 miles per hour
Step-by-step explanation:
Let the miles jogged be directly proportional to the hours taken hence we say that m=kh where m is miles, k is constant of proportionality and h is the number of hours. Making k the subject of the formula then
. Substituting miles jogged with 3.5 miles and hours with 7/8 hours as given then

Therefore, the constant of proportionality is 4 miles per hour
1/7 of 3 is not a way to find 7 divided by 3!
First of all if it is increasing then then it would start at the negative numbers. First is -1.2 second is 1/5 then it is 0.5 and finally 3/5
the angle that is vertical to ABI is EBH
