Step-by-step explanation:
During the Boston Marathon, a What are the unit rates for this situation? (How far can they run in 1 hour and how long does it take to run 1 mile?)
If a certain runner averages running 25 miles in 5 hours, then
25miles = 5hrs
To determine how far they can run in 1 hour, then;
X = 1hr
Divide both expressions
25/x = 5/1
5x = 25
X = 5miles
Hence the runner can run 5miles in an hour
Similarly if
25miles =1hr
1mile = y
25y = 1
Y = 1/25
Y = 0.04hrs
Hence the time taken to run 1mile is 0.04hrs
Answer:
(4,3)
Step-by-step explanation:
3x + 2y = 18
5x – 2y = 14
Add the two equations together to eliminate y
3x + 2y = 18
5x – 2y = 14
------------------------
8x = 32
Divide each side by 8
8x/8 = 32/8
x = 4
Now determine the value for y
3(4) +2y = 18
12 +2y =18
Subtract 12 from each side
12-12+2y = 18-12
2y = 6
Divide by 2
2y/2 =6/2
y=3
