Aman can now 6 km/hr in still
water. it takes him twice as long to
row up as to row down the river
and rate as stream

ANSWER:

2KM/H

EXPLANATION:

Time upstream: time downstream=2:1

speed is inversely proportional to time for a given distance

therefore

time upstream: time downstream =1:2

let speed upstream=x

speed downstream =2x

speed in still water =1/2(x+2x)=3x/2

3x/2=6

x=4

speed upstream =4km/h

speed downstream =2x=8km/h

rate of stream =1/2(8-4)=2km/h

HOPE IT HELPS

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
