Question
The speed of two cars A and B are in the ratio of 9:12
respectively. Car A travels 15 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?Solution
Let the speed of car A = 9x km/h and the speed of car B = 12x km/h. Here the time is constant. According to question, => 12x – 9x = 15 => 3x = 15 => x = 5 Distance travelled by car B = 12 × 5 = 60 km
