Question

The speed of a boat in still water is x km/hr and speed of the stream is 3 km/hr (i) Write the speed of the upstream, in terms of x (ii) Write the speed of the downstream, in terms of x (iii) If the boat goes 15 km upstream and 22 km downstream in 5 hours, write an equation in x to represent the equation in x to represent the statement (iv) Solve the equation to evaluate x

whoever solves it step by step will get brainliest answer

Answer 1

i)speed of upstream= (x-3)km/hr

ii)speed of downstream= (x+3) km/hr

iii) let, speed of stream= y km/hr

speed of boat in still water is = x km/hr

then we can set the equation like the picture i attached

note: i am not able to understand the question no 3
