a man can row 4.8 km / hr in still water. it takes him twice as long to row upstream as to row downstream. what is the rate of the current?
Choose the correct choice from the following options:
A) 1.9
B) 1.7
C) 1.2
D) 1.5
E) 1.6

divide(subtract(multiply(4.8, const_2), 4.8), const_3)
"speed of boat in still water ( b ) = 4.8 km / hr . speed of boat with stream ( down stream ) , d = b + u speed of boat against stream ( up stream ) , u = b – u it is given upstream time is twice to that of down stream . ⇒ downstream speed is twice to that of upstream . so b + u = 2 ( b – u ) ⇒ u = b / 3 = 1.6 km / hr . answer : e"
