Let the distance from Mumbai to Patna be x
speed=65 km/hr
from Mumbai to Patna time taken= d/s =x/65hrs
from Patna to Mumbai
speed=65 km/hr
from Patna to Mumbai time taken= d/s =x/60hrs
ATP
(x/60)-(x/65)=5hrs
(65x-60x)/3900=5hrs [lcm of 56 and 60=3900]
5x=5×3900
x=5×3900÷5
x=3900
distance between Mumbaiand Patna. is 3900 KM ANS
