Question

The speed of two cars A and B are in the ratio of 15:17 respectively. Car A travels 10 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?

A 68 km Correct Answer Incorrect Answer
B 57 km Correct Answer Incorrect Answer
C 85 km Correct Answer Incorrect Answer
D 76 km Correct Answer Incorrect Answer

Solution

Let the speed of car A = 15x km/h and the speed of car B = 17x km/h. Here the time is constant. According to question, => 17x – 15x = 10 => 2x = 10 => x = 5 Distance travelled by car B = 17 × 5 = 85 km
