This graph shows a trip on a bike trail. The trail has markers every 0.5 km showing the distance from the beginning of the
trail.
distance from beginning in kilometers
90.7 0.4 0.6 0.8
1.2 14 16 18 2 22 24 26 28 3 32 34"
time in hours
1. When was the bike rider going the fastest?
2. When was the bike rider going the slowest?
3. During what times was the rider going away from the beginning of the trail?
4. During what times was the rider going back towards the beginning of the trail?
5. During what times did the rider stop?

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
