the answer is 3.
Difference means subtract and each time youre subtracting 3 from the previous number
15:7.5:30
This is because 15 is the smallest, which is half of 4(30). And right between 15 and 30 is 7.5.

Answer:
Step-by-step explanation:
I hope these are people in vehicles travelling toward each other.
80 mh * t + 40 mph * t = 420 miles
The two vehicles are going to travel a total of 420 miles. B will cover a lot more ground than A, but together they will make 420 miles
80t + 40t = 420
120t = 420
t = 420/120
t = 3.5
So after driving 3.5 hours, the two cars will meet.
Slope = -1/2
