Question

a boat cover a certain distance downstream in 2 hour it cover the same distance upstream in 2.5 hour the speed of boat in still water 18km/h find the speed of the water also find the distance cover by road​

Answer 1

Answer:

Speed of boat in still water be u km/hr.

Then, distance covered downstream =(u+1)×8=8u+8

Distance covered upstream =(u−1)×10=10u−10

Since the distance both ways is the same,

8u+8=10u−10

⇒2u=18

⇒u=9 km/hr

∴ Distance covered one way =(9+1)×8 km

=80 km
