Determine the difference in the highest speed and the average speed
<em>Hence, the highest speed is 283.2 miles/hour faster than the average speed</em>
(3x+1) = 64
3x = 63
3x/3 = 63/3
x = 21
D 3 it is a 3 hours difference
Answer:
2
Step-by-step explanation:
Basically you don't need to find x to know the scale factor ,

(MN) and the same will happen with 5.5 and NO (which is 11 btw).
so you can write 2:1
Answer:
52
