The speed of two boats X and Y in still water is in the ratio of 4 : 3 respectively. Stream is flowing with speed (A) which is 3/4 times the upstream speed of boat Y. Boat X covers (B) km downstream distance in 4.5 hours. The downstream speed of boat Y is (C) more than the speed of boat X in still water. Boat Y covers 96 km upstream distance in (D) hours. The difference between the downstream speed of boat X and Boat Y is 7 km/hr.
Which of the following option is matched correctly?
1
A = 12 km/hr
2
B = 162 km
3
C = 4 km/hr
4
D = 8 hours
