The speed of the boat in still water is 24 km/h and the speed of the stream is 4 km/h. The time taken by the boat to travel from A to B downstream is 36 minutes less than the time taken by the same boat to travel from B to C upstream. If the distance between A and B is 4 km more than the distance between B and C, what is the distance between A and B
Let the distane between B to C = x km
Distance between A to B = (x+4) km
According to question,
x/(24-4)-x+4/(24+x) = 36/60
⇒x/20-x+4/28 = 3/5
⇒7x-5x-20/140 = 3/5
⇒2x-20 = 3/5×140
⇒2x=84+20
⇒x=104/2 = 52
Directions (next five questions) : Refer to the graph and answer the given questions.
Data related to number of projects handled
by two companies (A and B) during 5 years
What is the difference between the total number of projects handled by company A in 2003 and 2004 together and total number of projects handled by company B in 2005 and 2007 together
If the number of projects handled by company A increased by 20% from 2007 to 2008 and by 5% from 2008to 2009, what was the number of projects handled by company A in 2009
The project handled by company can be broadly classified into two types : Governmental projects and Non-governmental projects handled by company B in 2003 and 2004 is 127, what is the total number of governmental projects handled by the same company in 2003 and 2004 together
Out of the total number of projects handled by company A in 2005 and 2006 together, 20% were governmental projects. What was the total number of governmental projects handled by company A in 2005 and 2006 together
