Answer: 22 kph
<u>Step-by-step explanation:</u>
distance (d) = rate (r) x time (t)
UPSTREAM: d = 5 km, r = *x - y, y = 2 kph, t = 2t
DOWNSTREAM: d = 3 k, r = *x + y, y = 2 kph, t = t
*x is the speed in still water and y is the current of the water.
Upstream equation: 5 = 2t(x - 2) -->
Downstream equation: 3 = t(x + 2) -->
Set the equations equal to each other to solve for x:
Answer:
Distance from point (0,1,1) to the given line is zero.
Step-by-step explanation:
Given parametric equations of line,
x=2t, y=5-2t, z=1+t
To find distance from (0,1,1), we have to eliminate t from above equations so that,
whose direction ratioes are (l,m,n)=(3,2,-2) and distance fro point (a,b,c)=(0,1,1) is given by,
Distance between point (0,1,1) and (1) is zero. That is point 90,1,1) is lies on the line (1).
