## The distance by road between two towns A and B, is 216 km, and by rail it is 208 km. A car travels at a speed of x km/hr, and the train travels at a speed which is 16 km/hr faster than the car. Calculate : (i) The time taken by the car, to reach town B from A, in terms of x ; (ii) The time taken by the train, to reach town B from A, in terms of x ; (iii) If the train takes 2 hours less than the car, to reach town B, obtain an equation in x and solve it. (iv) Hence find the speed of the train.
