Q. If a boat can travel 50 km downstream in 2 hours, and the speed of the current is 5 km/h, what is the speed of the boat in still water?
A.
20 km/h
B.
25 km/h
C.
30 km/h
D.
35 km/h
Solution
Speed downstream = Distance/Time = 50 km / 2 h = 25 km/h. Speed of boat in still water = Speed downstream - Speed of current = 25 km/h - 5 km/h = 20 km/h.
Q. If a boat can travel 60 km downstream in 4 hours, what is the speed of the current if the speed of the boat in still water is 15 km/h?
A.
3 km/h
B.
4 km/h
C.
5 km/h
D.
6 km/h
Solution
Speed downstream = Distance/Time = 60 km / 4 h = 15 km/h. Speed of current = Speed downstream - Speed of boat in still water = 15 km/h - 15 km/h = 0 km/h.
Q. If A can complete a work in 12 days and B can complete it in 16 days, how long will it take for A and B to finish the work if they work together for 4 days?
A.
2 days
B.
3 days
C.
4 days
D.
5 days
Solution
Combined rate = (1/12 + 1/16) = 7/48. In 4 days, they complete 28/48 = 7/12 of the work. Remaining work = 5/12, which will take 5/7 days.
Q. If A can complete a work in 18 days and B can complete it in 27 days, how long will it take for them to finish the work if A works for 6 days and then B works for 6 days?
A.
10 days
B.
12 days
C.
14 days
D.
16 days
Solution
A's work in 6 days = 6/18 = 1/3. Remaining work = 2/3. B's rate = 1/27. B will take 50/9 days to finish the remaining work.
Q. If A can do a work in 15 days and B can do it in 25 days, how long will it take for A and B to complete the work if A works for 5 days and then B works for 5 days?
A.
10 days
B.
12 days
C.
15 days
D.
20 days
Solution
A's work in 5 days = 5/15 = 1/3. Remaining work = 2/3. B's rate = 1/25. B will take 50/3 days to finish the remaining work.
Q. If A can finish a work in 20 days and B can finish it in 30 days, how long will they take to finish the work if A works for 10 days and then B works for 10 days?
A.
15 days
B.
20 days
C.
25 days
D.
30 days
Solution
A's work in 10 days = 10/20 = 1/2. Remaining work = 1/2. B's rate = 1/30. B will take 15 days to finish the remaining work.
