A Man Can Row At 5 Km/hr In Still Water, If The River Is Running At 1

1.	A Man Can Row At 5 Km/hr In Still Water, If The River Is Running At 1 Km/hr It Takes Him 75 Minutes To Row To A Place And Back. How Far Is The Place?
Answer» SPEED downstream = (5+1)km/hr = 6 km/hr Speed upstream = (5-1)km/hr = 4 km/hr LET the required distance be x km. Then x/6 + x/4 = 75/60 = 5/4 =&GT; (2x + 3x) =15 => x =3. Required distance = 3 km. Speed downstream = (5+1)km/hr = 6 km/hr Speed upstream = (5-1)km/hr = 4 km/hr Let the required distance be x km. Then x/6 + x/4 = 75/60 = 5/4 => (2x + 3x) =15 => x =3. Required distance = 3 km.

Answer»

SPEED downstream = (5+1)km/hr = 6 km/hr

Speed upstream = (5-1)km/hr = 4 km/hr

LET the required distance be x km.

Then x/6 + x/4 = 75/60 = 5/4 =&GT; (2x + 3x) =15 => x =3.

Required distance = 3 km.

Speed downstream = (5+1)km/hr = 6 km/hr

Speed upstream = (5-1)km/hr = 4 km/hr

Let the required distance be x km.

Then x/6 + x/4 = 75/60 = 5/4 => (2x + 3x) =15 => x =3.

Required distance = 3 km.
