Topic: Rate (pls help me as soon as possible!) A car on its way from Town P to Town Q passed a truck which was traveling at a constant speed of 80 km/h after covering 3/7 of its journey. 3½h later, the car reached its destination, but the truck was still 40 km away from Town Q. If the truck had also started from Town P, how long would it take to travel from Town P to Town Q?
