Question

The speed of a stream is 2km per hour A boat travels between two ports downstream Inn 4 hours and upstream in 6 hours, find the speed of the boat and also the distance covered ​

Answer 1

Answer:

Let boat speed=x

stream speed=y=2kmper hour

downstream time =t1=4hours

upstream time=t2=6hours

t1+t2xy

t2-t1

10x2

2

boat speed =10km /hr

distance =10x4=40 km
