Philip jogged 3 1/2 miles yesterday in 7/8 of an hours what is his constant of proportionality

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
