Question

The representation of the statement " A man covers 20 km upstream and 30 km downstream in 15 hours" as an equation in two variables x and y,(where x kmph and y kmph are the speeds of the boat in upstream and downstream respectively) is​

Answer 1

Answer:

20/(x-y) + 30/(x+y) = 15

Step-by-step explanation:

Here is the equation to represent the time spent on travel

20/(x-y) + 30/(x+y) = 15

Note. x represents boat speed in still condition and y represents the speed of current. x+y is speed down the stream and x-y is speed upstream
