Question

the speed of a boat downstream is 36 km/hr and its speed upstream is 24km/hr. Find its Speed in still water and the rate of its stream.

if u explain it step by step I will give u mark as brainlist ​

Answer 1

Step-by-step explanation:

Let the speed of still wáter be x km/hr

then speed of water in downstream =x-36

and speed of wáter in upstream =x+24km/hr

ATQ(according to question )

x-36=x+24

x+x=24+36

2x=60

x=60/2

x=30km/hr

plz don't unfollow.

Answer 2

Answer:

If we taken x km/hr in still water

speed of downstream is 36 km/ hr

speed of upstream is 24 km/ hr

we know that in downstream X will subtract by 36

x- 36 km / hr

and in upstream x will plus 24

x+24 km/ hr

ATQ: x-36=x+24

x+x=24+36

2x=60

now divide 60/ 2

x=60/ 2

x=30 km / hr

I hope it's helpful pls mark me brain list and give me vote please
