Answer:
1.25 miles
Step-by-step explanation:
Lisa takes a night walk after dinner every night.
She walks 1/4 mile in 2 minutes.
Distance = 1/4 mile
Time, t = 2 minutes
For covering 1 mile,
1/4 mile = 2 minutes
In 1 minute she will cover 
For 10 minutes, she will cover 
So, she will cover 1.25 miles.
now, let's notice the minor arc of 26x°, let's recall that a circle has a total of 360°, thus if the minor arc is 26x°, then the major arc has to be the difference of 360 and that much, namely 360 - 26x.
Check the picture below.
The correct answer would be slightly over 33%.<span />
Answer:
Step-by-step explanation:
d = r * t
Let the rate of the boat in still water = x
Let the rate of the stream = y
Against the current
24 = (x - y)* 4 Divide both sides by 4
24/4 = x - y
6 = x - y
With the current
24 = (x + y )* 3 Divide both sides by 3
24/3 = (x + y)
8 = x + y
Put the two equations together
x - y = 6
<u>x + y = 8</u> Add
2x = 14 Divide by 2
2x/2 = 14/2
x = 7
x + y = 8
7 + y = 8
y = 8 - 7
y = 1
The boat is going 7 miles per hour
The stream is going 1 mile per hour.
