A and B travel from X to Y at the speed of 60 km/hr and 100 km/hr respectively . If B takes \(\frac{2}{5}\) hour lesser time than A , then what is the distance between the X and Y ?
Answer & explanation
Correct answer: option 4
Ratio A : B
60 : 100
Speed 3 : 5
Time 5 : 3
( Distance = Speed × Time , so ratio of speed and time is inverse to each other )
According to question ,
2R = 24 minutes
1R = 12 minutes
5R = 60 minutes = 1 hour
Distance = 60 × 1 = 60 km
