Directions: Study the data given below and answer the following questions. The pie charts shown below shows the distance covered by a boat moving upstream and downstream indifferent days of a week. And the table shows the speed of stream in km/hr. in different days of a week.
Question 5 : If the time taken by boat to travel upstream on Friday is 30 hours more than the time taken by it to travel downstream on Wednesday and the speed of boat in still water on Friday is 17 kmph, then find the upstream speed of boat on Wednesday? (speed of boat in still water is different on different days)
Let speed of the boat Upstream be U.
Speed of the boat Downstream be D.
Speed of boat in still water be B.
Speed of the stream be W.
U = B – W
D = B + W
Bfri = 17kmph
Wfri= 1kmph
Wwed = 6kmph
Distance travelled upstream on Friday = 14% of 4800 = 672 km
Upstream speed in Friday Ufri = Bfri – Wfri = 17-1 = 16kmph
Time taken to travel upstream on Friday = \\frac{672}{16}\\) = 42 hrs.
Distance travelled downstream on Wednesday = 11% of 2400 = 264 km
Time taken to travel downstream on Wednesday = 42-30 = 12 hrs.
Downstream speed in Wednesday Dwed = \\frac{264}{12}\\) = 22kmph
Also Dwed = Bwed + Wwed = 22kmph
Bwed = 22 – Wwed
Bwed = 22 – 6 = 16kmph.
Upstream speed of boat on Wednesday = Bwed – Wwed = 16 – 6 = 10kmph.
The question is "If the time taken by boat to travel upstream on Friday is 30 hours more than the time taken by it to travel downstream on Wednesday and the speed of boat in still water on Friday is 17 kmph, then find the upstream speed of boat on Wednesday? (speed of boat in still water is different on different days)"
Choice E is the correct answer
