Question

The sum of the speeds of a boat in still water and
the speed the current is 10 kmph. If the boat takes

pared to that upstream, then find the difference of
the speeds of the boat when travelling upstream
and down stream.
(a) 3 kmph (b) 6 kmph
(c) 4 kmph (d) 5 kmph
​

Answer 1

Answer:

6 kmph is the answer

Step-by-step explanation:

Reqd difference = downstream speed - upstream speed

= (10-4) kmph

= 6kmph
