George will arrive 20 minutes before Max
It takes Max 3 hours(180 minutes) to run 30 km .
The rate can be calculated as follows:
rate = 30 / 180 = 1/6 km/ min
George uses 2 hours 20 minutes(140 minutes) to run 30 km.
The rate can be calculated as follows:
rate = 30 / 140 = 3/14 km / min
If both are to complete a 15-kilometre race, Therefore,
Max time will be
1 / 6 = 15 / t
t = 15 × 6
t = 90 minutes
George time will be
3/14 = 15 / t
3t = 210
t = 210 / 3
t = 70 minutes
Time difference = 90 - 70 = 20 minutes
Therefore, George will arrive 20 minutes earlier than Max

Answer:
Because you did not give the slope, we cannot get the exact equation. However, using m as a substitute for slope, the point-slope form would be y - 7 = m(x + 4)
Step-by-step explanation:
We can find this equation through the use of the base form of point-slope form. Then we can plug in the point where we see fit.
y - y1 = m(x - x1)
y - 7 = m(x + 4)
Answer:
<em>-11, -10, -9, -8, -7, -6 and -5 </em>
Step-by-step explanation:
Given the inequality expressions
2x+9<0 and x>-12
2x+9<0
2x< 0-9
2x < -9
x < -9/2
x < -4.5
Since x >-12
-12 < x
Combining both inequalities
-12 <x < 4.5
<em>The integers between the intervals are -11, -10, -9, -8, -7, -6 and -5 </em>
So my take on this
15 + 3 -2(2 - 1)
15 + 3 -2(1)
15 +3 -2
18 - 2 = 16
