The speed of two cars A and B are in the ratio of 14:17 respectively. Car A travels 12 km less than the car B in the same time duration. What was the distance (in km) travelled by the car B during that time?
Let the speed of car A = 14x km/h and the speed of car B = 17x km/h. Here the time is constant. According to question, => 17x – 14x = 12 => 3x = 12 => x = 4 Distance travelled by car B = 17 × 4 = 68 km
