The distance between 2 cities is 180 km. The distance was covered by a car at 50 kph, by a bus at 45 kph, by a truck at 40 kph, and by a bicycle at 25 kph. How long did each take to travel the entire distance? Are speed and time directly or inversely proportional? What is the constant of variation? NEED HELP ASAP
