Answer:
Step-by-step explanation:
Man's speed with the current (Downstream speed)=speed of man(x)+speed of current
15km/hr=x+2.5km/hr
x=(15-2.5)km/hr
x=12.5km/hr
Man's speed against the current(Upstream speed)=speed of man-speed of current
Upstream speed=12.5km/hr-2.5km/hr
Upstream speed=10km/hr

the current speed of man is 15km/h ,
and the present speed is 2.5km/h
the speed of man compared to the present =speed of man(x)+present speed of man (2.5)
=) 15=x+2.5
=)15-2.5=x
so, x=1.0km/hr
and the present speed is 2.5km/h
the speed of man compared to the present =speed of man(x)+present speed of man (2.5)
=) 15=x+2.5
=)15-2.5=x
so, x=1.0km/hr
