Question
The speed of two cars A and B are in the ratio of 10:13
respectively. Car A travels 18 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 = 10x km/h and the speed of car B = 13x km/h. Here the time is constant. According to question, => 13x – 10x = 18 => 3x = 18 => x = 6 Distance travelled by car B = 13 × 6 = 78 km
