Answer:

  • k = 45 . . . miles per hour
  • k = 1/45 . . . hours per mile

Explanation:

One way we can relate distance and time is ...

time = k × distance

Then the value of k (the constant of proportionality) is ...

k = time/distance = 4 hours/(180 miles)

k = (1/45) hours/mile

__

Another way we can relate the variables is ...

distance = k × time

Then the value of k (the constant of proportionality) is ...

k = distance/time = (180 miles)/(4 hours)

k = 45 miles/hour
