Question 1150054: The distance between two cities is 180 km. The distance was covered by a car at a rate of 50 km/h, by a bus at 45 km/h, by a truck at 40 km/h, and by a bicycle at 25 km/h. How long did each take to travel the entire distance? Are speed and time directly proportional or inversely proportional? What is the constant of variation

Are speed and time directly proportional or inversely proportional? What is the constant of variation
============================
d = r*t
distance = rate (or speed) * time
------------
You can do the calculations.
