Answer:
9.3
Step-by-step explanation:
if both travel at same speed they will take equal distance and time to reach the middle and collide.
hence, 27/2 =13.5km
speed=distance/time
time = distance/speed
time= 13.5/87 = 0.15517mm hr
0.15517×60 = 9.31minutes
The generic equation of the line is:
y-yo = m (x-xo)
The slope is:
m = (y2-y1) / (x2-x1)
m = (- 2-0) / (3-0)
m = -2 / 3
We choose an ordered pair
(xo, yo) = (0, 0)
Substituting values:
y-0 = (- 2/3) (x-0)
Rewriting:
y = (- 2/3) x
Answer:
The equation of the line is:
y = (- 2/3) x
To write a fraction as a mixed number, we need to figure out how many times 3 will go into 19. Divide 19 by 3 to get our whole number.
19/3 = 6.
We have 6 0/3 as our mixed number so far, but we have 1/3 left over from the 19/3, since 18/3 = 6.
Add 1/3 to 0/3.
Your answer is 6 1/3.
I hope this helps!
Answer:
Yosef finished the mile in 9 minutes.
Distance = 1 mile
Demetrius' speed = 7.5 miles per hour
Demetrius' time = Distance/speed
= 8 minutes
Demetrius finished the mile first by taking 1 minute less than Yosef's finishing time.
