Question
A and B travel the same distance at speed of 9 km/hr and 10 km/ hr respectively. If A takes 36 minutes more than B, the distance travelled by each is
Answer: Option B
Answer: (b)Let the distance between A and B be x km, then$x/9 - x/10 = 36/60 = 3/5$$x/90 = 3/5$$x = 3/5 × 90$ = 54 km.Using Rule 9,Here, $S_1 = 9, t_1 = x, S_2 = 10, t_2 = x - 36/60$$S_1t_ 1 = S_2t_ 2$$9 × x = 10(x - 36/60)$9x = 10x - 6 = 6Distance travelled = 9 × 6 = 54 km
