Answer:
12 mph
Step-by-step explanation:
The relationship between jogging speed and walking speed means the time it takes to walk 4 miles is the same as the time it takes to jog 8 miles. Then the total travel time (0.75 h) is the time it would take to jog 1+8 = 9 miles. The jogging speed is ...
(9 mi)(.75 h) = 12 mi/h . . . average jogging speed
__
<em>Check</em>
1 mile will take (1 mi)/(12 mi/h) = 1/12 h to jog.
4 miles will take (4 mi)/(6 mi/h) = 4/6 = 8/12 h to walk.
The total travel time is (1/12 +8/12) h = 9/12 h = 3/4 h. (answer checks OK)

<em>Comment on the problem</em>
Olympic race-walking speed is on the order of 7.7 mi/h, so John's walking speed of 6 mi/h should be considered quite a bit faster than normal. The fastest marathon ever run is on the order of a bit more than 12 mi/h, so John's jogging speed is also quite a bit faster than normal. No wonder he got tired.
5x = # of games won
2x = # of games lost
The total number of win and lose is 147.
5x + 2x = 147
Solve for x,
5x +2x=147
7x = 147
x=21
The ratio of games won: #of games lost is 5:2
5x21=105: 2x21=42
105 wins: 42 lost
Answer:
105, I think if not please tell me it isn't!
The correct answer is A.
write the equation in point slope form first and then solve to slope intercept form
I think it’s 1) organic, 2) sustainable, 3) vertical, and 4) consistent
