A car can travel 320 km in the same amount of time a bus can travel 280 km. Suppose that the speed of the bus is 23 km per hour slower than the speed of car. Find the that distance = velocity time. Student solution. The distance that the bus has travelled is: while the distance that the car has travelled is: dear If v denotes the velocity of the car, then the velocity of the bus in terms of v is bus= If t denotes the travel time, then in terms of v, the time of travel for the bus: and the time of travel for the car: t%3D Then after we cross-multiply we can write in terms of v: O-0
