If a boat is moving in upstream with velocity of 14 km/hr and goes downstream with a velocity of 40 km/hr, then what is the speed of the stream ?
(a) 13 km/hr (b) 26 km/hr (c) 34 km/hr (d) none of these
Read Solution (Total 7)
-
- if the downstream is a km/hr and upstream is b km/hr then speed of stream is 1/2(a-b)
so, 1/2(40-14)=13 km/hr is the answer - 12 years agoHelpfull: Yes(16) No(1)
- speed of the stream=(downstream-upstream)/2
ie; (40-14)/2=13
ans is option A - 12 years agoHelpfull: Yes(6) No(0)
- data insufficient as speed of stream not given.

- (a) 13 km/hr
- 12 years agoHelpfull: Yes(0) No(0)
- 40-14=26
26/2=13km/hr - 12 years agoHelpfull: Yes(0) No(0)
- speed of stream = (40-14)/2=13 km/hr
option - (a) - 7 years agoHelpfull: Yes(0) No(0)
- upstream is A, down stream is B then speed of stream is A-B/2
- 7 years agoHelpfull: Yes(0) No(0)
