A man can row upstream at 25 kmph and downstream at 35 kmph, and then find the speed of the man in still water?

A. 60 kmph
B. 10 kmph
C. 30 kmph
D. 5 kmph
Explanation:
US = 25
DS = 35
M = (35 + 25)/2 = 30

A. 10 kmph
B. 5 kmph
C. 20 kmph
D. 22 kmph
Explanation:
M = 15
S = 5
DS = 15 + 5 = 20

A man can swim in still water at 4.5 km/h, but takes twice as long to swim upstream than downstream. The speed of the stream is_________?

Basic Maths Mcqs, Boats and Streams, Mathematics Mcqs /
A man can swim in still water at 4.5 km/h, but takes twice as long to swim upstream than downstream. The speed of the stream is_________?

A. 3
B. 7.5
C. 2.25
D. 1.5
Explanation:
M = 4.5
S = x
DS = 4.5 + x
US = 4.5 + x
4.5 + x = (4.5 – x)2
4.5 + x = 9 -2x
3x = 4.5
x = 1.5

C. 8 kmph
D. 3 kmph
Explanation:
DS = 6
US = 4

A. 7 km/h
B. 5 km/h
C. 3 km/h
D. 2 (1/2) km/h
Explanation:
100 — 10 DS = 10
? —- 1
75 —- 15 US = 5
? —– 1 S = (10 – 5)/2
= 2 2 ½ kmph
