Question

A man rows downstream 32 km and 14 km upstream, and he takes 6 hours to cover each distance. What is the speed of the man​

Answer 1

Answer:

upstream 14km

down stream 32km

time6hours

14/6-x=32/6+x(6)

14/6-x -32/6+x=6

14(6+x)-32(6-x) =6

6*6- x square

84+14x+192-32x/36-xsquare=6

276-18x /36-xsquare=6

276-18x=192-6xsquare

6xsquare-18x+84=0

6
