Question

a man can row with the stream at 10km/hr. and against the stream at 5 km/hr. Man's rate in still water is?​

Answer 1

Answer:

7.5 km/hr

Step-by-step explanation:

Let the man's speed is M and that of stream flow is S.

then M + S = 10

M - S = 5

adding these two equations we get,

M + S + M - S = 10 + 5

2M = 15

M = 7.5 km/hr

Answer 2

Answer:

5 km obviouslyyyyyyyy
