70

50

35

I don't know.

Answer 1

THE constant of proportionality, k for the relationship between miles and hours traveled is 35.

Let :

Miles = m

Hours traveled = h

The relationship between m and h is :

m α h

m = kh

Picking a pair of values for miles and hour

Miles = 70 miles

Hours = 2 hours

70 = 2k

Divide both sides by 2 to isolate k

70/2 = k

k = 35

Therefore, the constant of proportionality, k is 35
