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 :
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 :
[A]48 km
[B]54 km
[C]60 km
[D]66 km
54 km
Let the distance between A and B be x km, then
$latex \frac{x}{9} – \frac{x}{10} = \frac{36}{60} = \frac{3}{5}&s=1$
$latex => \frac{x}{90} = \frac{3}{5}&s=1$
$latex => x = \frac{3}{5}\times 90 = 54 km.&s=1$
Hence option [B] is correct answer.
