Question

steamer goes downstream and covers the distance between two parts in 4 hours will it cover the same distance upstream in 5 hours if you speed of the stream is 12km/hr find the speed of the stream is will still water cheak your solution​

Answer 1

Answer:

as he streamer goes down stream

therefore , x+y

for upstream = it is x-y

total time taken to go upstream and down stream = 4+5 =9hrs

speed = distance / time

speed x time =- distance

x+y + x-y * 9 = distance

2x * 9 = 12

x = 12/9 * 2

= 0.66 km/hr

= 66m/hr
